Abstract
This paper presents a picture coding scheme with switchable dynamic quantizers. The image data compression technique is a hybrid of subsampling, pyramid coding, block truncation coding, interpolative coding, dynamic quantization and differential quantization. In addition to the differential quantizer, there are three other quantization modes. According to image activity, each block of the subsampled image can be quantized and coded dynamically in one of four modes. The coding technique can be adapted for progressive transmission of images and can be extended to color images.
