The following are two different images that are encoded using the same algorithm. The images are each in a 5 by 5 grid of pixels where each pixel is black, white, red, green or blue.
The image on the left gets encoded and compressed down to 21 digits while the image on the right gets compressed down to 25 digits. Although the same algorithm was used to encode and compress these images, why are the end results a different length?
a. The algorithm was probably used improperly in the image on the right, causing it to be a longer length than it should have been.
b. Because this is a lossy compression, sometimes information is lost during the compression.
c. The amount of size reduction from compression depends on the amount of redundancy in the original data.
d. The image on the right uses more colored squares and therefore requires more digits to represent the pixels.
