摘要：Image compression is the application of data compression on digital images.
Image compression can be lossy or lossless. In this paper it is being attempted to
implement basic JPEG compression using only basic MATLAB functions. In this paper
the lossy compression techniques have been used, where data loss cannot affect the
image clarity in this area. Image compression addresses the problem of reducing the
amount of data required to represent a digital image. It is also used for reducing the
redundancy that is nothing but avoiding the duplicate data. It also reduces the storage
area to load an image. For this purpose we are using JPEG. JPEG is a still frame
compression standard, which is based on, the Discrete Cosine Transform and it is also
adequate for most compression applications. The discrete cosine transform (DCT) is a
mathematical function that transforms digital image data from the spatial domain to the
frequency domain.
