Abstract :This paper introduces the concept of Blind Deconvolution for restoration of a digital image and
small segments of a single image that has been degraded due to some noise. Concept of Image Restoration is
used in various areas like in Robotics to take decision, Biomedical research for analysis of tissues, cells and
cellular constituents etc. Segmentation is used to divide an image into multiple meaningful regions. Concept of
segmentation is helpful for restoration of only selected portion of the image hence reduces the complexity of the
system by focusing only on those parts of the image that need to be restored. There exist so many techniques for
the restoration of a degraded image like Wiener filter, Regularized filter, Lucy Richardson algorithm etc. All
these techniques use prior knowledge of blur kernel for restoration process. In Blind Deconvolution technique
Blur kernel initially remains unknown. This paper uses Gaussian low pass filter to convolve an image. Gaussian
low pass filter minimize the problem of ringing effect. Ringing effect occurs in image when transition between
one point to another is not clearly defined. After removing these ringing effects from the restored image,
resultant image will be clear in visibility. The aim of this paper is to provide better algorithm that can be helpful
in removing unwanted features from the image and the quality of the image can be measured in terms of
PSNR(Peak Signal-to-Noise Ratio) and MSE(Mean Square error). Proposed Technique also works well with
Motion Blur.

I. Introduction
An Image is a word that is derived from a Latin word ‘imago’ which is a representation of visual
perception in a 2-D or 3-D picture that has a similar appearance to some objects and a Digital Image is a
numeric representation of a 2-D image [1].
1.1. Image Restoration:
Image Restoration is a process of undo all the unnecessary effects known as ‘blur’ or ‘noise’ that has
been added into an image by various reasons like misfocus of the camera, large distance between camera an
object, capturing a picture of a moving object known as motion blur, Gaussian blur by using Gaussian filter etc.
The process of adding noise into a digital image is known as Convolution and the process of restoring a
convoluted image is known as Deconvolution. There are basically 3 types of blur: a) Motion blur, b) Gaussian
blur, c) Average blur [2]. The main objective of Image Restoration is to sharpen the features of an image in such
a way that it can clearly be seen by a person. However Image Restoration differs from Image Enhancement. In
Image Enhancement we do not make use of any degradation model or we do not need to know about the process
which is degrading the image while in case of Image Restoration, degradation model is necessary to restore an
image. In Image restoration we try to find a degradation model and then by using that model, we apply the
inverse process and try to restore the image [3].
Degradation model of Image Restoration:

Some applications of Image Restoration are:
1.1.1. In medical science such as CT, MRI, Ultrasound etc.
1.1.2. Sharpness.
1.1.3. Contrast Enhancement.
1.1.4. Denoising etc.
1.2. Image segmentation: Image segmentation divides an image into various parts or segments also known ‘set
of pixels’ or ‘Super Pixels’ in which each pixel or picture element exhibits similar attributes. There are various
techniques for image segmentation such as region based segmentation, edge/ boundary based segmentation etc
[4]. The segmentation technique used in this paper is based on Pixels known as Pixel Based Segmentation. In
this technique a digital image is divided on the basis of the resolution of an image. Resolution is the number of
pixels on the horizontal axis and the vertical axis of the image. Segmentation of image depends on the size of
the input image. Larger is the size of the Input image and more is the number of segments of that image. This
paper considers 9 segments of the input image.
1.3. Blind Deconvolution: Blind Deconvolution is a technique of restoration of a degraded/ blurred image
without having any knowledge of blur kernel or PSF(Point Spread Function) of an image. A kernel is a mask in
the form of small matrix used to blur an image. This small matrix is known as Convolution Matrix. In this
technique of restoration, blur kernel is unknown that is why it is known as ‘Blind’. Deconvolution is a technique
to sharpen or deblur a blurry image, and collectively it is known as Blind Deconvolution Technique. A kernel is
a 2D matrix that is used to blur an image also known as Convolution Matrix. It can be represented as:
Y=k*X+n; (1)
Where, X is the input gray image. Y is the degraded image. K is the kernel or convolution matrix that is added
with the input image X to transform it into the blurry image called Y. * is the convolution operator.
The goal of Blind Deconvolution is to inverse the above process and to recover both X and k [5]. This technique
restores the blurry image by calculating PSF of the degradation by using three techniques and chooses the one
that provides better restoration result. Techniques are:
1.3.1. Undersized PSF.
1.3.2. Oversized PSF.
1.3.3. INIT PSF.
The performance of restoration is measured by calculating PSNR (Peak Signal to Noise Ration) value
of the restored image. Higher is the value of the PSNR, more will be the quality of restored image.
II. Proposed Methodology
This methodology firstly convert a digital colored image into gray image (if it not a gray image) and then add
Gaussian blur into that image. Gaussian blur is added into the image by using following function:
H=fspecial (grayimagename, hsize, sigma); (2)
Where, hsize can be a vector or a scalar. This function returns a Gaussian filter of size ‘hsize’ with standard
deviation ‘sigma’. fspecial () creates Gaussian 2D filter by using following formula:
hg(n1,n2)=𝑒
−(𝑛12+𝑛 22)
2𝜎2
(3)
h(n1,n2)=
hg(n1,n2)
ℎ 𝑔𝑛2𝑛1
(4)
Where hg is a Gaussian Filter having n1 number of rows and n2 number of columns. 𝜎 is a standard deviation.
After adding Gaussian Blur into a Gray image, the technique of segmentation is applied on the image.
Number of segments depends upon the size of segments. Larger is the size of image more will be the number of
segments.
Architectural model of proposed technique is shown in figure Fig(2):](https://image.slidesharecdn.com/f017614146-151204054904-lva1-app6891/85/An-Efficient-Approach-of-Segmentation-and-Blind-Deconvolution-in-Image-Restoration-2-320.jpg)

Fig (2): Architectural Model Of Proposed Technique.
Algorithm of Proposed Technique:
Step 1: Read the Original Gray Image I.
Step 2: Add blur into image I say G.
Step 3: Apply pixel based segmentation on image I and corresponding image G. ( No. of segments depend upon
the size of Input image.
Where Original Gray Image I contains, I=(I1,I2,I3,I4……) segments and Blurred Image G contains,
G=(G1,G2,G3,G4…..) segments.
Step 4: Store all segments found in step 3 into a folder.
Step 5: for all G=(G1,G2,G3,G4….) apply Blind Deconvolution Algorithm.
Step 6: Remove ringing effects from the restored segments for accuracy of results.
Step 7: Measure performance of the result by calculating PSNR values.
III. Quality Measurement
Quality of an image in proposed technique is generally measured in terms of PSNR (Peak Signal-to-Noise
Ratio) and the MSE(Mean Square Error).
Peak Signal-to-Noise Ratio (PSNR) is a mathematical measure of image quality based on pixel
difference between two images [6]. It is generally measured in terms of decibels(db). Higher the PSNR value of
the image, better is the quality of that image. PSNR of two images can be calculated as:
PSNR=10log
𝑀𝐴𝑋 2
𝑀𝑆𝐸
(5)
Where, MAX is 255 for 8 bit images. MSE is Mean Square Error
Mean Square Error (MSE) is calculated by averaging the squared intensity of the original image and
the output image pixels [7]. It can be calculated as follows:
MSE=
1
𝑀𝑁
[𝑋 𝑖, 𝑗 − 𝑌 𝑖, 𝑗 ]2𝑁−1
𝑗=0
𝑀=1
𝑖=0 (6)
IV. Experimental Results
4.1.Without Segmentation: Proposed technique is applied on Four Gray Images without segmentation having
different image types. Following table shows original gray images, their corresponding degraded images and
images obtained after applying Blind Deconvolution Technique:

V. Conclusion
In this proposed technique we have applied Blind Deconvolution Algorithm on multiple images of
different sizes having different format such as .jpg, .png, .tiff. Proposed Technique is compared with the existing
method and provides better results in terms of PSNR and MSE. Proposed technique reduces complexity of the
system than the existing method because this technique does not use any Edge Detection Method like Canny
Edge Detection, Sobel, Prewitt etc. to improve the quality of the image as compared to existing method. This
Technique is also applied on multiple segments of a single image and provides good results. But this Technique
has some limitations. It does not work for all type of Gaussian Blur added into the image.
VI. Future Work
Many other techniques of image processing can also be applied with Blind Deconvolution Algorithm to
provide improved results than the proposed technique. Methods can be developed that can work for all types of
blur added into the image. Proposed Technique consists of only nine segments of a single image. It can also be
applied on more than nine segments of images in future. Segments that are not restored properly can be further
be improved.
