Lossy compression and they can be used to compress text‚ video‚ audio etc. Keywords—LossyCompression‚ Lossless Compression‚ Huffman Algorithm‚ DCT and JPEG. I. INTRODUCTION Compression is a process by which size of data is reduced. There are two main types of data compression lossless and lossy compression. These are further divided into different methods which are Huffman‚ run-length and Lempel-ziv. JPEG file compression applied with the help of DCT matrix. Sometimes the given data contains some

compound image. The pictorial blocks are compressed using discrete haar wavelet transformation and text/graphics colors are mapped to primary colors using color quantization algorithm and the resulting index values are then compressed using lossless Huffman coding technique. The compressed image is then encrypted using Advanced Encryption Standard algorithm. The proposed model provides several benefits like low complexity‚ high compression ratio‚ and a high PSNR value .Moreover it ensures that the transmission

that guides these thoughts‚ actions‚ and behaviors. Motivation refers to a set of factors that “activate‚ direct‚ and maintain behavior‚ usually toward some goal” (Huffman‚ 2010‚ p. 406). Theories or sources involved in driving motivation emphasize biological‚ psychological‚ social forces‚ and the environment (Deckers‚ 2010; Huffman‚ 2010). This essay thoroughly discusses motivation‚ examines a couple of sources that contribute to motivation‚ emphasizes the relationship between motivation and behavior

processing (Huffman). The short-term memory is the part of the memory that temporarily stores and processes information from the sensory memory and holds it until it decides if the information will be sent to the third stage or long-term memory (Huffman). The short-term memory stores a mixture of perceptual analyses information (Huffman). The short-term memory works in different ways to increase its small capacity; it uses rehearsal and chunking to be able to remember more things at once (Huffman). Rehearsal
