decompress using IPP

durgadas_puranik · ‎04-22-2005

I have compressed images (JPEG 2000 lossless). I need to decompress it using IPP 4.0. There are following functions in IPP 4.0.

Functions for JPEG coding:

Color Conversion Functions

Combined Color Conversion Functions

Quantization Functions

Combined DCT Functions

Level Shift Functions

Sampling Functions

Planar-to-Pixel and Pixel-to-Planar Conversion Functions

Huffman Codec Functions

Functions for JPEG2000 coding:

Wavelet Transform Functions

JPEG2000 Entropy Coding and Decoding Functions

Component Transform Functions

My doubt is what all function I need to call for decompressing the the images which I have?

Can somebody give solution.?

Thanks in advance

Durga

Hi Durga,

In IPP v4.0 we had simple sample for JPEG2000 encoder. But I'm glad to say that in IPP v4.1 (which is available right now) we significantly improve this sample. Now it supports encoding and decodingfor both lossless and lossy modes. There will be even more improvements in next version, IPP v5.0 beta which comes soon.

So, you can download IPP v4.1 libraries and samples from here
