Improved JPEG based GPS picture compression
Yair Wiseman · Advanced science and technology letters · 2015
Abstract. Pictures used by GPS devices are usually overly large to be stored as Bit Map, so they are by and large compressed. The common compression method is JPEG; however JPEG assumes that the average color of beginning of each blocks line is usually similar to the average color of end of its preceding blocks line. Many times this assumption is incorrect for GPS picture. This paper suggests a way to change this method to an improved method that is more suitable for JPEG based GPS images.
