Log data reduction for variable bandwidth data link
I have an embedded system which generates samples (16bit numbers) at 1 milli second intervals. The variable uplink bandwidth can at best transfer a sample every 5ms, so I am
looking for ways to adaptively reduce the data rate while minimizing the…

Image processing with lossy compression
If we compare image procesing of the losslessly compressed images with the image processing of the lossy compressed images, does the latter provide the results comparable to the former one.
I am asking this question because the images prodiced by…
