Now many DSP systemsneed the fixed-point FFT to improve the speed of image processing .The precision in FFT calculation brought by the word length should be thought much of in the system designing . A precision analysis was put forward in this paper about the fixed-point FFT , and the max...
在空间域中的滤波很简单，只需要将待滤波的图像和滤波器核进行卷积运算；而在频域的滤波则需要先将图像通过傅立叶变换转换到频域上，然后乘以适当的滤波器，最后，通过傅立叶反变换转换到空间域中。这两种方式在不同的情况下有着各自的缺点和优点，而且在ＣＰＵ上的实现已经是成熟通用的方法广为人们熟知。然而由于这...

Image processing depends on compression which helps in reduction of file size for large data transmission in a stipulated and reduced time. Wavelet analysis provides one of the common goals of image compression, i. e. the signal or image clearance and simplification, which are part of denoising ...
