1. 
   The human eye is far more sensitive to color than it is to grayscale
   
2. 
   The colour range of the light is different from that of the pigment, some of which can not be represented by the colour pigments; the difference in material and process.

3.4) Edge dectection plays a major role in many image processing applications.This is a sample program to perform edge dectection by using a jpg image.the program is simple.

3.5) Spatial resolution is the number of pixels in a unit area of an image, indicating the resolution of the spatial details of the image;

Gray resolution refers to the level of gray between pure black and pure white, referring to the resolution of the image to the details of gray changes)

4. Section

In the flat area of the image, a small sub-image is taken as a histogram and compared with the existing noise model

(b) Average(Mean) filter

Median filter： g(x, y) Median[x1, x2 ,..., x9 ]
Mean filter can remove the noise of the suddenly changed points, but the cost of it is that
the image is fuzzy to some extent, and median filter can remove the isolated points and line noise and keep the edge of the image.



Average filter： Median filter
