image data compressionの例文

• Similarly, current high-efficiency digital color image data compression schemes such as JPEG and MPEG store RGB color internally in subsampling with the chroma channels ( typically to 4 : 2 : 2 or 4 : 1 : 1 ratios ), which it aids to reduce the resultant file size.
• In the fields of image processing, computer vision, and computer graphics, Heeger worked on motion estimation and image registration, wavelet image representations, anisotropic diffusion ( edge-preserving noise reduction ), image fidelity metrics ( for evaluating image data compression algorithms ), and texture analysis / synthesis.
