EuclideanColorDistance class
Algorithm class for comparing images with euclidean distance.
Images are resized to the same dimensions (if dimensions don't match)
and euclidean difference between src1 RGB values and src2 RGB values
for each pixel is summed.
sum(sqrt(([src1i.red - [src2i.red)^2 + ([src1i.blue - [src2i.blue)^2 +
([src1i.green - [src2i.green)^2)
- Best with images of similar aspect ratios and dimensions
- Compare for exactness (if two images are identical)
- Returns percentage difference (0.0 - no difference, 1.0 - 100% difference)
