Image Compression is a method, which reduces the amount of space required to store the image. The Discrete Cosine Transform (DCT) is a method that transforms a signal or image from spatial domain to frequency domain. This technique is widely used in image compression. In this paper, we present a lossless DCT compression technique for two-dimensional images. In several scenarios, the utilization of the presented technique for image compression results in comparable or better performance, when
