Implementation of JPEG compression algorithm with JFIF header being appended.This project involves writting code for following steps : Chroma subsampling,partitioning ,level shifting,DCT,quantization,zigzag scanning(involves DC differential coding &

They are the programs of uniform quantization and non-uniform quantization. In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by

A template matching algorithm for Chord Recognition. It matches a given chroma with 180 chord patterns

采用基于梯度的算法，通过matlab实现高动态范围成像。高动态范围图像，相比普通的图像，可以提供更多的动态范围和图像细节，根据不同的曝光时间的低动态范围图像，利用每个曝光时间相对应最佳细节的低动态范围图像来合成最终高动态范围图像，能够更好的反映人真实环境中的视觉效果。这里采用的高斯模糊展示了高动态范围图像中超出取值范围的数值也是有用的，即使它们在转换成低动态范围图像的时候通常都要被裁掉。在原始的高动态范围图像中，这些像素都有非常大的亮度值。当图像模糊的时候，周围的像素亮度被“拉高”并且在色度映射
