An image has four possible gray levels, named r1, r2, r3, and ra. The probabilities of each gray level are: p(r1) = 0.066666666666667, p(r2) = 0.34666666666667, p(r3)= 0.42666666666667, and p(ra) = 0.16. If variable length coding is used to compress the image, the shortest code will be associated with which probability?Select one:O a. 0.8533Ob. 0.0667O. 0.4267Od. 0.2133Oe. 0.0333

For an image of size 32x32 and a filter of size 5x5, if you want the convolution result to keep the original image size, what's the padding size in pixels? a) 5 b) 2 c)10 d) 3 explain.
For three objects, sorted from front to back with the colors C0 = 0.2, C1 = 0.8, C2 = 0.5 and the background color Cbg= 1(white). Compute the final pixel color by front to back and back to front compositing for the following alpha values α0=0.2, α1=0.4, α2=0.1. For the background, you can assume αbg = 1 (fully opaque). You can think of the background as a fourth layer.
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.

Consider a room with world coordinate system U-V-W as shown. Two cameras are mounted in the room, forming a stereo pair. The world coordinate origin is in one corner of the room, with UV-W axes shown. The "Left" camera Cl is located at world coordinates (10,1,3) and it's xl-yl-zl axes are oriented as shown. The "Right" camera Cr is located at world coordinates (7.1,2) and its xr-yr-zr axes are oriented as shown. Both cameras have a focal length of 1. U (1) What is the 3x4 matrix that maps 3D points in world coordinates into 2D points in film plane coordinates (when points are represented as homogeneous coordinates), for the left camera CI?

An input image has the size of 140x140 and we use a filter (kernel) with the size of 20x20. We then convolve the input image with the filter. a. If we do not use padding and stride is 1, the output size will be axa, where a is b. If we use padding of 5 with stride 1, the output size will be bxb, where b is c. If we use no padding and stride is 5, the output size will be cxc, where c is d. If we use padding of 5 with the stride 5, the output size will be dxd, where d is
