Search Results for "compression"

Simple, fast implementation of LZW (Lempel–Ziv–Welch) data compression algorithm in C. - Console encoder/decoder tools - OS independent - Could be used in embedded projects - Works with raw code-stream LZW features: - Hardcoded dictionary size - Variable code size - Code search is performed by hash table and embedded in dictionary linked lists (encoder) - No dynamic memory allocation

Encode bitmap(bmp) file with run-length encoding(RLE), just like RLE4 and RLE8, but extend to RLE16, RLE24 and RLE32. Usually, this project will be used in GUI of embedded system, to make the image files smaller, and save the IO bandwith. If the GUI support JPG or PNG, the compression ratio is much better than RLE, but how about the embedded system encounters both caculate limitation and IO bandwidth limitation? Try this project, I hope it can make a banlance between caculation and bandwidth. But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap file data, the ratio can larger than 1, only when the same color continuously repeats in one line, it will gain a smaller compression ratio.

This is an application that streams data from the Microsoft Kinect or cameras like it over a network. The program is Intended to be used in robotics applications where the controller cannot use such cameras directly due to hardware/software limitations--such as lacking usb ports or appropriate drivers--or in situations where the camera is not in close proximity to the device that needs to access it. Given that the controller can accept data from over the network, another embedded controller...
