Cashmere Fiber Identification, And Computer Image Of The Fine Wool Fiber

The traditional way of distinguishing wool and cashmere is using Light microscope . Using scanning electron Microscope is a new distinguishing way recently. Though Scanning electron Microscope advances than Light microscope, it doesn't achieve fully automatic. It can't process image, so it can't get scale's area and scale's circumstances which are two important data. And it can't distinguish automatically. This paper is to remedy the defect of the Scanning electron Microscope. The distinguishing of fiber will be finished by computer. At first it process image, then it process data, at last it will finish distinguish automatically.Digital image processing, i.e. image processing with computer, as a usual, the image can't be analyzed by computer immediately because computer only can processes digital but not image. So an image must be converted digital before it be recognized. We can get the locations of two points with VB, and we can calculate the length between the two points. Now we can get the fiber's diameter and the scale's height.The color of image is composed by red green and blue. They are called three basic colors. When the scale of red green and blue is the same, it is called the grayscale image. If we want area and circumstance, at first we must test the edge of fiber scale. Now we have many way to get it, but the fiber scale in this paper is not enough obvious to distinguishit, we get the edge man made in Photoshop. Then we fill black in it so as to convert a image which only have two colors: black and white. The area can be calculated by counting dot of black. We can get edge when we only keep edge as black in the same way.We must save the data of fiber, so we establish two database. It must appear when need.Process the data, Analyze the unknown fiber with the fiber in the database, we can know it belong to.
