ffmpeg - Mathematically lossless encoding and decoding of RGB24 image sequence -

-

i trying encode rgb24 image sequence mathematically (not merely visually) lossless video. huffyuv suggested on many online forums tried following.

ffmpeg -i frames\%06d.png  -vcodec huffyuv test.avi

the resulting video decoded frames again using ffmpeg

ffmpeg -i test.avi outframes\%06d.png

however, input , output frames not bit-by-bit identical promised huffyuv here. idea how can accomplish this? eventual goal read video file using opencv willing cross bridge later once obtain losslessly encoded video file.

this question mentions attempt obtain lossless h264 avi , summary of responses seems indicate h264 cannot accomplish lossless encoding.

once again, emphasize, i interested in bit-by-bit identical encoding, not visually similar. large file sizes acceptable large compression/decompression time.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

Image
i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
