Due to rapid growth of digital media and the subsequent need for reduced storage and to transmit the image in an effective manner Image compression is needed.Image compression is the application of Data compression on digital images. Data compression is the technique to reduce the redundancies in data representation in order to decrease data storage requirements and reduce communication costs. Reducing the storage requirement is equivalent to increasing the capacity of the storage medium and hence communication bandwidth. Thus the development of efficient compression techniques will continue to be a design challenge for future communication systems and advanced multimedia applications. Fast and efficient coding algorithms are needed for effective storage and transmission, due to the popularity of telemedicine and the use of digital medical images.Run-length encoding is a popular compression scheme which is used extensively to compress the attribute values in column stores. The basic characteristics of image like transmission rate, bandwidth, redundancy, bulk capacity and co-relation among pixels makes basic compression algorithms mandatory. The research exploration in the field of image compression is huge.Run length coding is the standard coding technique for compressing the images, especially when images are compressed by block transformation.
