- Pulsecode modulation using matlab/PCM using. To perform non uniform quantization one needs to pass the signal. Encoding is done to transmit the signal.
I'm trying to quantize an image 8 bits to 4 or 2-bits uniformly. I searched internet, interestingly I could not find what I want exactly. Then I wrote an simple code for it myself. I'm curious about whether there is a build-in function in MATLAB which convert 8-bit image to 4-bits uniformly . Casio exilim ex z60 user manual. My results using the methods from internet is not good. Am I doing something wrong when I use these methods? Thank you in advance.
- Method from internet giving strange results
- Method writen by me. I'm putting code to clarify what I want to do.

I point you to this https://stackoverflow.com/questions/12723699/changing-image-bit-depth-using-matlab it can be done. This particular post is only for png, but if I'm not mistaken all image types have the depth parameter so they can likely all be changed in a similar manner

Uniform Quantization Of Images
For your particular problem, since your images are already grayscale you would do something like
Aterciopelados discografia. EDIT #2: While reducing the 'bits' to display the image, the 'colormap' is made by taking the average of each range You dont know youre beautiful song mp3 download. I kept the original answer because it still works and may suit someone elses needs in the future.
Matlab Quantization Function
For this solution, rather than using evenly spaced values for our 'colormap' we actually use the gray value that is the average over the specified range Used kurzweil pc3.
ex
Excel 2010 mac download free. to convert to 1 bit image we have two ranges 0,128 and 128,256
replace all values between 0,128 with the average value between 0,128
replace all values between 128,256 with the average value between 128,256 Download minion 3 movie.
