A New Format for Representing and Encoding Images
- 技術優勢
- Better compression rate than JPG code, requires 5X less file size It extracts image structure, which is useful for later stage image processing
- 技術應用
- Image compression, storage, and transmission Image processing techniques
- 詳細技術說明
- Researchers at UCLA have circumvented this serial procedure and developed a method for encoding images that require a much smaller file size. Their technique is based on the development of a primal sketch which is extracted from an image based on the portion of the image with distinguishable elements. A library is generated from these elements which can then be applied to the entire image for compression. In addition, because the method is evaluative and retains key features of the original image, it benefits subsequent image processing techniques.

Background
JPEG is a standard image compression algorithm as the method by which the digital image is stored and is commonly used in digital cameras. The compression process relies on a series of algorithms that approximate the color spectrum in predefined regions of pixels. Because, the process is serial and is performed in the same manner across the whole image, the compression rate has no optimization routine and therefore suffers.
