1. Create a java program that will print out the following statistics about an image (gray-level image of one channel). A color image must be converted to gray level using the utility functions provided to you. a. Overall mean of the image b. Overall variance of the image c. The dynamic range of the image

2. As an application of the mean, you will also create a function that will take an image, a top-left corner coordinate, a block size and a sub-block size and return an image that has the passed block blurred (by blurring the subblocks within it) a. For example, you would specify the block at I,J of a given block size (for example 32). You will then identify the block and break it into sub-blocks (for example of size 4). For each subblock, you will then compute the mean and replace all the pixels in the subblock by their mean. b. The subblocks will be blurred because you replaced every pixel with its mean. c. You can access the subblocks with a double loop that starts at I,J and increment by the subblock size

for( i

for(int j=J; j

{

Identify subblock

Calculate mean

Replace each pixel by the mean with proper cast and clipping
