It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient. -It shows what a jpeg compres

这个是自己编写的霍夫变换直线检测MATLAB程序，可以用于道路分道线检测。是一种非常简单容易实践的程序。-This is a hough line detection algorithm which can be used to road lane detection. this method is very simple and easy to realize
