image compare

1 New Member
hi !!
i need to compare images in vb.net. i am unable to find which component i am supposedly to compare.(RGB or the YCrCb ).

my aim is to compare two similar images taken at different resolution and find additional data from them to create a new high resolution image, basically its called superresolution.

please help.

i tried comparing only the Y component for YCrCb but its give different results for color and black pixels...

Do you have an algorithm that you use?
Depending on the image type and compressiong (bmp, png, jpg, etc) the .GetPixel() command will return slightly different things.
Well, it returns an instance of the Color object, but sometimes the alpha channels are used as well as the RGB values.
Not sure what you need.
