Hybrid Image Compression Using DWT, DCT and Huffman Coding Techniques
Here in this hybrid model we are going to proposed a Nobel technique which is the combination of several compression techniques. Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level. The reduction in file size allows more images to be stored in a given amount of disk or memory space. It also reduces the time req...
متن کاملImage Compression using DCT and DWT - Technique
This paper provides comparison between two image compression technique such as DCT and DWT. Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) are the most commonly used transformation. DCT has high energy compaction property and requires less computational resources. On the other hand, DWT is multi-resolution transformation. PSNR and Compression ratio are one of the parameter...
متن کاملImage Compression Hybrid using DCT , DWT , Huffman
Image compression literally means reducing the size of graphics file, without compromising on its quality. Depending on whether the reconstructed image has to be exactly same as the original or some unidentified loss may be incurred, two techniques for compression exist. Image compression is an essential technology in multimedia and digital communication fields. Ideally, an image compression te...
متن کاملMedical Image Compression Using Hybrid Techniques of DWT, DCT and Huffman Coding
Image compression plays a crucial role in medical imaging allowing efficient storage and transmissions by reducing the amount of data required to represent the digital image. The main goal is to achieve higher compression ratios and minimum degradation in quality. To decrease the storage space, the use of different compression techniques is justified by some medical imaging modalities generate ...
متن کاملComparision of Dct and Dwt of Image Compression Techniques
– Multimedia data requires considerable storage capacity and transmission bandwidth. The data are in the form of graphics, audio, video and image. These types of data have to be compressed during the transmission process. Large amount of data cannot be stored if there is low storage capacity. Compression is minimizing the size in bytes of a graphics file without degrading the quality of image t...
