0 likes15 views
This document summarizes a research paper on predicting facial attributes without using landmark information. It describes the AFFAIR method which uses a global transformation network and part localization network to predict attributes. The global network learns an optimized transformation for each input face for attribute prediction. The part network localizes the most relevant facial regions for specific attributes. The global and local representations are then fused to predict attributes with high accuracy without requiring external landmark points. Experimental results on standard datasets show the AFFAIR method achieves state-of-the-art performance in landmark-free facial attribute prediction.

Abstract – Prediction of the face attributesisverychallenging
because of complex variation in face. Most of the systems
which are used for predicting the attributes of face are unable
to give the precision as these methods are depending on the
landmark detection and canonical positions. The dependency
on landmark detector is unable to give satisfactory results on
unconstrained faces with large pose angles, occlusion or
blurriness which reduces the performance of attribute
prediction. The system explained here use an AFFAIR method
that gives the face attribute prediction. By learning a global
transformation technique and adaptive part localization
technique, system provides the most relevant part for
predicting a specific attribute on the face. TheAFFAIRlearnsa
good transformation for each input face image directly for
attribute prediction with greater accuracy.
Key Words: AFFAIR, Landmark Detector, Attribute
Prediction, Global Transformation, Part localization.
1. INTRODUCTION
Describing people depending on their feature points like
gender, age, hair style and clothing style is an important
problem for many applications in face analysis. Previously
Detection-Alignment-Recognition (DAR) method [1] is used
for detection of the face attributes with landmark detection
from images. As this method depends on the quality of
landmark detection, it results reduce the performanceofthe
method as it unable to give the fine result on unconstrained
faces. Some of the author uses a pre-trained deep
Convolutional Neural Networks (CNN)[4][6][1] for face
recognition tasks to obtain global face representation and
binary linear SVM classifiers are built on the global face
representations to classify face attributes. The previous
methods use global methods in which entire object for
representation learning and attribute prediction is done
without part information and thelocal methodwhich extract
features from relevant regions or parts for attribute
prediction.
This study aims to investigate the possibility of optimizing
facial landmark detection and alignment which are
complicated tasks. Here we are studying AFFAIR method[1]
which is an aggregation of global and local methods for
attribute prediction. AFFAIR provides an end-to-end
learning framework for finding the appropriate
transformation. The global transformation is used to detect
face and generates transformation parameters tailored for
the original input face. Part LocNet is used to focus on the
most relevant part of the face forattributeprediction.Finally
by integrating both global and local representations, we can
predict the facial attributes with no requirement of external
landmark points for alignment.

3. SYSTEM DESIGN
Human face attributeestimationhasreceiveda largeamount
of attention in recent years in visual recognition research
because a face attribute provides a wide variety of salient
information such as age, gender e. t. c. The fig.1 shows the
architecture of the system. The working of the system is as
follows:
Fig.1: System Architecture
Input image: User uploads images using live camera.
Face is detected from the input image and given to the
AFFAIR framework as an input. The AFFAIR method is
an aggregation of both global and local methods for
attribute prediction that integratesbothglobal andlocal
representations and requires no external landmark
points for alignment.
lAndmark Free Face AttrIbute pRediction method:
lAndmark Free Face AttrIbute pRediction (AFFAIR)
method learns a global transformation and part
localizations on eachinputfaceend-to-end.Itmainlyhas
two important components:
Global Transformation Network: The global
transformation transformstheinputfacetotheone
with an optimized configuration for further
representation learning and attributes prediction.
Global transformation consists of two parts:Global
TransNet and Global Representation Learning Net.
The global TransNet was followed by global
representationlearningnetwork whichwasusedto
consider all the facial attributes simultaneously.
Thus, the global TransNet and the global
representation learning net is trained end-to-end
for attribute prediction.
The global TransNet in AFFAIR takes the detected
face as input, and produces a set of optimized
transformation parameters ‘Tg’ tailored for the
original input face for attribute representation
learning. The transformation maps the globally
transformed face image with the input image via-
(1)
Because of this, the globally transformed face
images were obtained pixel by pixel. The pixel
value at location (xi
g, yi
g) of the transformed image
was obtained by bilinear interpolating the pixel
values on the input face image centered at (xi
input,
yi
input).
After this, the globally transformed face image in
the pixel format is then given as input to the Global
RepresentationLearningNet whichsimultaneously
considers all the facial attributes. The output face
from the global TransNet was denoted by ꞘθT
g(I).
Then the global face representation learning net,
parameterized by θF
g, maps the transformedimage
from the raw pixel space to a feature space
beneficial for predicting all the facial attributes. All
the facial attributes were denoted by ꞘθF
g, θT
g(I).
Part Localization Network:
Part LocNet was used to localize the most relevant
and discriminative parts for a specificattributeand
make attribute prediction. LocNet can access the
whole face.
The part LocNet predicts a set of localization
parameters and it focuses on relevant part on the
face through learned scaling and translating
transformations. For example, the shape of the
eyebrow or the appearance of the goatee, etc. are
very small attributes on the face which can be
predicted by part localization. The set of part
localization parameter was denoted as Tp and the
correspondence between the parts to the globally
transformed face image was modeled by the
following equation which links the pixel value at (
xp
i, yp
i) on the output partial face image to the pixel](https://image.slidesharecdn.com/irjet-v6i799-191101071624/85/IRJET-Prediction-of-Facial-Attribute-without-Landmark-Information-2-320.jpg)

values centered at location ( xg
i, yg
i) on the globally
transformed face
image.
(2)
Part LocNet is also end-to-end trainable. It positionsthe
focus window to a relevant part on the face through
learned scaling and translating transformations. Then
the locally transformed images were then processed by
the Local Representation Learning Net for more than
one or all attributes of the face. The additional
parameter to generate the transformation, Tpi, in the
part LocNet for the ith attribute is denoted by θT
pi. Thus
the generated transformation was given by-
Tpi = ꞘθT
pi, θF
g, θT
g (I) (3)
Global-Local Feature Fusion : In this phase, both
global and local representations were integrated by
finding a good global transformation to rectify the face
scale, location and orientation, and identify the most
discriminative part on the face for specific attribute
prediction without requiring external landmark points
for alignment. The global and local features are
generated by the global representation learningnetand
the part representation learning net which were fused
for attribute prediction.
Attribute Prediction: The global and local features
were generated by the global representation learning
net and the part representation learning net,
respectively and were fused to get attribute prediction.
Finally after combining the Global-Local features, the
specific attribute prediction can be done.
4. RESULTS
Fig.2 gives the experimental results of global
transformation and part localization.
The globally transformed images possess 3 × 3 grids on
the transformed face boxes. We can see that the two
eyes lie in the center grid. The figure 2 demonstrates
that the global TransNet is able to generate good global
transformations in the sense that the two eyes are
centered in the transformed faces images.
Fig.2: Results of Global TransNet[1]
Also, the localization results from the part LocNets for
all the 8 facial attribute categories in the CelebA dataset
are shown in fig.3. Each column shows a facial attribute
category and each row shows one test image, where the
original test face images are displayed in the first
column. The next columns show the localization results
on the globally transformed face images. The boxes
indicate the output from the part LocNets. One can see
on top of the globally transformed faces, thepartLocNet
indeed localizes the most discriminative partoftheface.
For example, the eye region is localized for predicting
attributes “Arched Eyebrows”, “Bags Under Eyes”,
“Eyeglasses”, etc. The nose region is localized for
attributes “Big Nose” and “Pointy Nose”.

5. ADVANTAGES AND DISADVANTAGES
Advantages:
AFFAIR model is able to localize the specific
part for prediction of the facial attribute with
the use of transformation-localizationnetwork.
The AFFAIR model integrates both global and
local representations, by removing the need of
external landmark points for alignment.
AFFAIR focuses on the local region and learns
more discriminative representation for better
attribute prediction.
AFFAIR does not require face alignment as
preprocessing and provides state-of-the-art
results for the CelebA, LFWA and MTFL
datasets.
Disadvantage:
This method gives better performanceinall the
cases but when the personwearsthemask then
we cannot detect the face attributes.
6. CONCLUSION
The landmark free Face Attribute prediction (AFFAIR)
system is addressed in this paper which does not](https://image.slidesharecdn.com/irjet-v6i799-191101071624/85/IRJET-Prediction-of-Facial-Attribute-without-Landmark-Information-3-320.jpg)
