Problem 3: The histograms of two images are illustrated below. Sketch a transformation function for each image that will make the image have a better contrast. Use the axis provided below to sketch your transformation functions. 1/128 1/200 64 192 255 100 155 255
The issue: You are programming a graphics filter that filters each individual picture. The definition of a pixel is a triplet of real integers (R, G, and B), each of which ranges from 0 to 255. For the filtering methods to function properly, real numbers must be used. However, after looking at the software, you find that they only require two digits of accuracy. Any extra numbers are just unnecessary.
Please write python codes to smooth an image by using median filter and Bilateral filter separately. You should give your codes, the input image and its outputs.
Wirte a matlab code to plot the 3D image of a helix: Use the following parameters and equations that define the axes in 3D: p=0.199; Pitch distance (distance between the turns)a=0.02999500; Radius of the helis wireb=0.191; Radius of the helixn = 5, is the number of helis turns. δ = atan(p/(2*pi*b)); The pitch anglex’ = b + a cos(Ө)y’ = -a sin(Ө) sin(δ)x = x’ sin(ф)+y’ cos(ф);y =-x’ cos(ф)+y’ sin(ф);z = p*ф/(2*pi)+a*sin(Ө)*cos(δ);
The Issue: You're writing a graphics filter that runs each picture through a filter. Each pixel is specified as a triplet of real numbers (R,G,B) ranging from 0 to 255. To do their task, the filtering algorithms must operate on actual numbers. However, when you examine the software, you will notice that they only require two digits of accuracy. Any extra digits are unnecessary.
Motion History Image (MHI) technique uses a frame differencing inside to generate M(t). In its original form SFD is used. Instead of SFD, we can use a) ABS, b) TFD. Write pseudo-code for each case separately.

Laplacian Image Pyramid A Laplacian image pyramid is a multi-scale representation of a single image that highlights intensity discontinuities at multiple scales. It is obtained by convolving an image with a Gaussian mask and subtracting the smoothed image from the original one. The next level of the pyramid is obtain by repeating this process on the smoothed image after it is down-sampled. Create a 3 level Laplacian image pyramid of the woods image (after conversion from uint8 to double format), using a Gaussian with a standard deviation of 1.5, using "same" as the shape parameter for the conv2 function, and resizing by a scale factor of 0.5 using nearest-neighbour interpolation. Display the images in the pyramid as subplots in the same window.

Lesson: Application of Computer Graphics Given an orthographic camera with direction d, up u, and center c properties (size is fixed to 1), show the formula for generating a ray for point (x, y) in the screen (0,0 <= x, y <= 1,1). Remember, a ray has an origin and a direction.
