摘要：Recently, many researchers started to challenge a longstanding practice of digital photography: oversampling followedby compression and pursuing more intelligent sparse samplingtechniques to compress the image and produce the high quality ofimage and thus, it can be transmitted without any change tocurrent image coding standards and systems. In this papercomparison between three image compression techniques isdiscussed. The first technique is Lossless HypersCompression System-Based on HW/SW Codesign,implementation of a lossless compression system for hyperspectralimages on a processor-plus-field-programmable gate array(FPGA)-based embedded platform is used. Software executiontime of compression algorithm was profiled first to conclude thdecision of accelerating the most time consuming interbandprediction module by hardware realization.The aim of this paper is to compare various imagecompression techniques that overcome the drawbacks of thesecompression techniques that discussed here. Second aim, byof discussing compression studies, is to highlight and evaluate theutility of these methods in various domains. Thisimage compression techniques will be very useful for thedevelopment and improvement of new techniques
