I am using 8 bit grayscale image for SPIHT compression(shown in the link) with input value rate =1.
Will there be any compression occur in the output?
I am using the code shown in the link
https://in.mathworks.com/matlabcentral/fileexchange/4808-spiht
Of course there's always compression in each pixel, but how many bit reduce depents ini the color RGB pixel
grascale image from RGB too, so my point is whether Grayscale or color image, definitely compression occur
we can do compress without lossing the quality of an image by using Human Visual System.
@Robbi Rahim : But while using the code mentioned in the above link.I got compression ratio =1 for the input value rate(bpp) =1
@U. Dreher : But in the case of SPIHT gray scale image compression, if the input metric bpp=1, I am getting compression ratio of ' 1' .And I got compression ratios more than 1, for bpp
