The compression algorithm for JPEG is called Discrete Cosine Transform (DCT). This method transforms the image data into frequency components, separating low and high-frequency information. The algorithm then reduces the less important high-frequency components, which results in a smaller file size. ...
The paper introduces the JPEG compression algorithm firstly, including its history and the basic situation of this stage, compression principle, and so on. Referring to the JPEG compression method, the paper focuses on the basic tenets of Huffman coding and run-length coding and their specific app...
Therefore, instead of eight by eight blocks, we can generalize the JPEG algorithm and divide an image into trapezoid and triangular blocks according to the shapes of objects and achieve higher compression ratio. The simulations show that, when the bit rate is fixed, our proposed algorithm can ...
JPEG files are compressed image files. They support 24-bit color and can be substantially more compact than many other file types. The JPEG compression algorithm is lossy and is not as well suited for line drawings and other textual or iconic graphics, and thus the PNG and GIF formats are ...
