This software program compresses images through a command-line interface, allowing users to reduce the file size of their images quickly and easily. The program is typically used by professionals or businesses that need to optimize their images for web or email use.
Hcompress is an image compression software that was designed specifically for the Space Telescope Science Institute. The software utilizes a unique method that includes a wavelet transform called the H-transform, which is a generalized Haar transform that works in two dimensions.
The process used by Hcompress also involves the quantization of the images, allowing for the noise to be removed while still retaining the signal on all scales. Finally, the software employs quadtree coding of the quantized coefficients for ultimate compression.
Overall, Hcompress is an innovative and effective image compression package that has proven to be especially beneficial for the field of astronomy, thanks to its thoughtful and specialized approach to data compression.
