HW 2

Task 1:

I used the following images for the experiment:

And the following is the histogram distribution of the images:

Task 2:

For task 2, I just randomly picked 8 pictures from Flickr’s interesting pictures gallery. The histogram for these pictures are not as clearly distinguishable as opposed to the pictures in task 1, as a result the top two matches was all over the place.

Based on the results of both experiments, the use of histogram is useful in identifying similarities for images with a large variance of darkness, brightness, etc. but is not that effective with regular images where the histogram patterns are not as obvious. However, the technique can still be useful in conjunction with other similarity measures.
