Abstract - The quality evaluation process of fruits and
vegetables are used to measure the color, shape, size, and
external defects which will be helpful for the people. Quality
evaluation of fruits and vegetables can be of destructive and
nondestructive types. In the formertheentirefruit isdestroyed
while evaluating the quality. In non-destructive quality
evaluation the fruits and vegetables are not destroyed while
evaluating its quality. Now-a-days, various mechanical,
optical, electromagnetic, and dynamic non-destructive
methods are gaining importance due to ease in operations,
faster turn over and reliability. In this, we are inspecting the
quality of fruits based on size, shape and color. One of the
important quality features of fruits is its appearance.
Appearance not only influences their market value, the
preferences and the choice of the consumer, but also their
internal quality to a certain extent. Color, texture, size, shape,
as well the visual flaws are generally examined to assess the
outside quality of fruits.
Key Words: Camera, Filtering, ANN Technique, Geometric
Feature Extraction, Canny Edge Detector, etc.
1.INTRODUCTION
Quality components of fruits and vegetables are classified
into the external such as size, color, shape, external defects
etc. and the internal such as sugar content, acid content,
firmness, maturity, internal breakdowns etc. The color and
firmness of fruits affect the product appearance and
consumer acceptability. Non-destructive methods are
effective than traditional conventional methods as non-
destructive methodsaremainlybasedon physical properties
which correlate well with certain quality factorsoffruitsand
vegetables. Non-destructive methodsareadvantageousover
traditional destructive methods as they do not rupture the
fruit tissue, can be used to assess internal variables of fruits.
Quality of fruits and vegetables is based on its
sensory properties, nutritional value, safety and defects.
Various methods are used for external and internal quality
evaluation. Methods to measure fruit quality can be of
destructive and non-destructive. With destructive methods,
a sample of fruit must be measured in order to estimate the
quality of a batch: besides the economical loss, due to fruit
destruction, there is also the problem of how the sample is
representative of the whole batch. If we use the internal
quality factors and do not destroy the fruit while measuring
them, such approaches are referred to as nondestructive
quality evaluation. By applying this method, itcanovercome
possible discrepancies between different batches and
samples of fruit, without destroying a certain amount of
sample fruit post. Agriculture has an importantroleinsocio-
economic development of India. Various types of fruits
produced through-out the year.
2. LITERATURE REVIEW
Inkyu Sa et al. [1] presents a new approach for fruit
identificationusingdeepconvolutional neural network.Fruit
detection system has been trained with a many number of
images using a DeepConvolutional Neural Networks(DCNN)
and rapid training was done about 2 hours on a GPU named
as K40. Fruit identification from image was acquired from
two models :Near-Infrared (NIR) and color RGB Faster
Region-based CNN usescolorRGBimagestoperformgeneral
object detection. They perform supervisedmachinelearning
algorithms that teach a model of object interest. They had
perform fine-tuning of the VGG16 network whichwasdepnd
on the pre-trained ImageNet model.
To detect defected apple fruits A. Raihana et al. [2]uses
AFDGA-Apple Fruit Detection, Grading and Analyzation
techniques. Modify Watershed Segmentation was used to
segment the defection and analyze the fruits using Gray
Level Co-occurrenceMatrix basedfeatureextractionmethod,
and finally classify the images by support vector machine
(SVM) in terms of the its features. Textural, statistics and

some geometrical features has utilized to classify the apple
fruits and grade it. Mean, Variance and a portionoftheshape
features [area, perimeter] has taken for FPGA examination.
Simulation results obtained from MATLAB and VLSI had
compared for performance evaluation.
M. Bulanon et al. [3] presents algorithm to automatic
recognize the fruits for a machine based vision system that
teaches a robotic harvesting. Fuji apple fruit images which
was increased by using the red color threshold. Results
explain that apple fruit had the greatest red color threshold
within the object in the image. The histogram was obtained
by the increased image had a bimodal distribution for the
object as a fruit portion and the background such as leaves
and branches portion. Maximum grey level threshold of the
red color difference between the fruit, leaves and branches
was determined by the maximum threshold value.
3. SYSTEM ARCHITECTURE
3.1 IMAGE ACQUISITION
An image is analysed as it is clicked. Then the user is given
tools to discard that he considers noise. The image
acquisition is done using a digital camera anditisloadedand
saved using MIL software. MIL works with images captured
from any type of colour (RGB) or monochrome source
(Grey). MIL supports the saving and loading of images. It
supports file formats such as TIF (TIFF), JPG (JPEG), BMP
(bitmap), as well as raw format. Here the input image got is
an RGB image.
3.2 PREPROCESSING
Basically, the images which are obtained during image
acquisition may not be directlysuitableforidentificationand
classification purposes because of some factors, such as
noise, weather conditions,andpoor resolutionofimagesand
unwanted background etc. We tried to adopt the established
techniques and study their performances.
3.3 FILTERING
The purpose of filtering is to smooth the image. This is done
to reduce noise and improve the visual quality of the image.
Often, smoothing is referred to as filtering. Here filtering is
carried out by median filter since it is very useful in
detecting edges. The best known order-statistics filter is the
median filter, which replaces the value of a pixel by the
median of the gray levels in the neighborhood of that pixel.

3.4 SEGMENTATION
The purpose of image segmentation is to divide an
image into meaningful regions with respect to a particular
application. The segmentation is based on measurements
taken from the image, may be grey level, colour, texture,
depth or motion. Here edge-based segmentation is properly
suitable. As edge detection is a fundamental step in image
processing, it is necessary to point out the true edges to get
the best results from the matching process. That is why it is
important to choose edge detectors that fit best to the
application. In this way canny edge detector is chosen.
3.5 FEATURE EXTRACTION
Feature extraction is defined as grouping the input
data objects into a set of features. The features extracted
carefully will help to extract the relevant information from
the input data in order to perform the feature matching
using this we can reduce the representation input size
instead of the full size input. Here clustering process has
been used to extract features form good and bad fruits.
3.6 IMAGE CLASSIFICATION
Classification for the image is the neststepandused
for the classification of the colour of the fruit depends onthe
data given by image segmentation part,onthe basisofwhich
further fruit colour is classified.
4. SYSTEM DESIGN
4.1 FRUIT SIZE DETECTING AND GRADING
 Colour Detection:
In the process of fruit color is detected according to RGB
values [8], here fruits are sorted according to color and size.
So for e.g.two fruits are considered sayApple,Tomatohaving
red color and Kevi(Guava) having green color, so in this step
work is going tofind out color of a fruit by using RGB values

of an image taken from the camera, this image can be
processed by using python.
 Color Detection Algorithm:
1) Start
2) Read the inputcolorimageusingimreadfunction.
3) Read the input pixel of color image in three
different planes (RGB) and
store it into three variable r, g, and b.
4) Read the small region of fruit to detect color of
fruit.
5) Store in different variable r1, g1, b1.
6) Calculate the mean of r1, g1, b1 and store into
variable r2, g2, b2.
7) Compare the value with threshold.
8) If b2>threshold, Color detected is black.
9) If r2>threshold, Color detected is Red.
10) End.

6. IMEPLEMENTATION AND RESULT
The hardware used for this a multiple camera for
image acquisition, a computer, a light source and a black
background. A Webcam is a video camera that feeds or
streams its image in real time to or through a computer to a
computer network When "captured" by the computer, the
video stream may be saved, viewed or sent on to other
networks via systems such as the internet, andemailedasan
attachment. Webcam typically include a lens, an image
sensor, support electronics, and may also include a
microphone for sound. Now, the capability is bigger and not
impossible to increase in the near future. An image is

analyzed as it is clicked. Then the user is given tools to
discard that he considers noise.

7. CONCLUSIONS
In India normally grading isdonemanually.Thegrading and
sorting is mainly based on external and internal quality
factors. The external factors are color, size, volume, shape
and texture. Among these color and size are mainly used for
features for grading of fruits. Grading based on Size is very
easy method and less expensive method used for sorting of
apples, tomatoes etc. In color based grading Direct color
mapping technique is flexible and efficient method. For skin
defect detection at higher resolution wavelets are used and
at low resolution curvelets are best option. The grading
based on size manually can be performed but result obtain
are not accurate and grading and sorting based on other
external factor is not possible to done manually. So there is
need of automation in fruit quality inspection.
External properties of fruits like color, size, shape,
texture and different defects areveryimportantattributesof
fruits for classification and grading. Now a days due to
advancement in machine vision and availability of low cost
hardware and software, manual work of fruit classification
and grading has been replaced with automated machine
vision systems. Other reason of non-destructive automation
can be its ability to produce accurate, rapid, objective and
efficient results over manual work.
