Yes, I understand why the initial compression of a bitmap (not necessarily a .BMP) to a JPEG is lossy, via the quantization step after DCT. But if I decompress a JPEG back to a new bitmap, and then re ...

Effective compression is about finding patterns to make data smaller without losing information. When an algorithm or model can accurately guess the next piece of data in a sequence, it shows it’s ...

Music streaming and image / video transfer are technologies that are indispensable in modern society, but in order to use these technologies, it is indispensable to 'compress a huge file size to a ...

ADCs and DACs are generating a flood of sampled data that are creating high-speed bottlenecks on busses and in networks. Part 1 of this article described the use of compression algorithms that take ...

Figure 1. JPEG 2000 applications. Click here to see an enlarged diagram. The JPEG 2000 standard, finalized in 2001, defines a new image-coding scheme using compression techniques based on wavelet ...

Image compression, once the domain of the PC, is becoming pervasive in embedded environments. This trend is largely a result of the increased processing power and multimedia capabilities of new DSPs.
