Using Low-pass to Filter the Color Image in MATLAB
Jingcheng Li · Computer Knowledge and Technology · 2006
The date of the color image is too big, the load of working is increasing when it is transporting.One of the image's characteristics is that the proportion of low frequency is much more than the high frequency and most of the information is concentrate in the low frequency.If the requirement about the image's quality is not strict,we can use the low-pass to filter the high frequency which is the edge of the image,the skip and the noise will reduce the data of the image.It is easier for the next step.In this paper, we introduce a way of filteringthe color images in low-pass filter,exampled dealing with the true color image.
