Write an expression for 2-D continuous convolution.
In the context of pattern recognition and image processing, the 2-D continuous convolution is a mathematical operation used to combine two functions (such as an image and a filter or kernel) to produce a third function. The expression for the 2-D continuous convolution is given by:
f(x,y)∗g(x,y)=∫−∞∞∫−∞∞f(u,v)g(x−u,y−v) du dvf(x, ___ ______ ____ ______ _______ __________ ___ ________ _______ ____ ___ ____.

An automobile manufacturer is automating the placement of certain components on the bumpers of a limited-edition line of sports cars. The components are colour coordinated, so the robots need to know the colour of each car in order to select the appropriate bumper component. Models come in only four colours: blue, green, red, and white. Find a solution based on imaging and determine the colour of each car, keeping in mind that cost is the most important consideration.
A binary image contains straight lines oriented horizontally, vertically, at 45°, and at - 45°. Give a set of 3 x 3 masks that can be used to detect 1-pixel breaks in these lines. Assume that the intensities of the lines and background are 1 and 0, respectively.
Define the terms 'Sampling' and 'Quantization' in context of digital image processing. A medical image has size 8x8 inches, the sampling reduction is 5 cycles/mm, calculate the number of pixels required for the medical image.
Consider the two image subsets, S₁ and S2, shown in the following figure. For V = {1}, determine whether these two subsets are (i) 4-adjacent, (ii) 8-adjacent, or
(iii) m-adjacent.
What is Discrete Fourier Transform (DFT)? Find DFT of the function:
Two images, f (x,y) and g (x,y), have histograms he and hg. Give the condition under which you can determine the histograms of
i) f(x,y)+g(x, y)
ii) f(x,y)-g(x,y)
iii) f(x, y)xg(x, y)
iv) f(x,y)+g(x,y)
The white bars in the test pattern shown are 7 pixels wide and 210 pixels high. The separation between bars is 17 pixels. What would this image look like after application of
i) A 3×3 arithmetic mean filter?
ii) A 7x7 arithmetic mean filter?
iii) A 9×9 arithmetic mean filter?
