[0022] This disclosure describes techniques for encoding data to compress image data to a reduced size. The techniques can be particularly effective in transcoding images to a reduced size for transmission. The transcoding techniques described herein can be used in many applications. One such application that may utilize the techniques is transmission via wireless networks. For example, a user may take digital pictures using a mobile phone with image capture capabilities, such as a so-called camera phone or video phone. Typically, the captured digital pictures are high-resolution images, eg, high-resolution JPEG images. However, in order to send the captured image to another phone, it may be necessary to transcode the image file of the high-resolution image to a smaller file size (eg, lower resolution) to comply with the wireless network service provider's transmission Required or better suited to the screen size and color limitations of the receiving device.
