Compression of raster image from digital camera is frequently applied to reduce the irrelevance and redundancy of the image data in order to be able to store or transmit the image data efficiently. Suppose the image has a resolution of 858 525 block of pixels and represented as 24-bit RGB color with 8-bit per color component that are going to be compressed using the JPEG compression. Calculate the number of bytes necessary to store this image data in the YUV model with 4:2:0 chrominance subsampling and provide the compression rate. [5 marks]
