 The APR is an adaptive image representation designed primarily for large 3D fluorescence microscopy datasets. By replacing pixels with particles positioned according to the image content, it enables orders-of-magnitude compression of sparse image data while maintaining image quality. However, unlike most compression formats, the APR can be used directly in a wide range of processing tasks - even on the GPU!
