Description: 1.首先将原始图档(如图三)由RGB彩色模型转换成HSI彩色模型，取其 I 亮度模型。
2.再萃取出亮度值大于0.999之部份，进行数次膨胀与侵蚀运算后，即可取得火焰部份(如图四)。
3.图四之火焰影像进行边缘运算，并找出边缘之每一点坐标，再将坐标排序，取最小值作为链码的启始点(如图五之红色星号)。
4.链码产生的方式：沿边缘依逆时针的顺序扫瞄下一个边界值，并依序输出链码(如图七)。-1. First, the original drawing (Figure 3) from RGB color model into HSI color model. I lesser brightness model. 2. Then extracted brightness values greater than 0.999's part of several expansion and erosion of analyzing, flame can get some (Figure 4). 3. Figure 4's flame edge imaging operations, and to identify edges coordinates of each point, and then coordinates scheduling, As for the minimum chain code of the initial point (Figure 5's Red Star). 4. Chain Code of ways : counterclockwise along the edge according to the order under a scanning boundary value, Output and order chain code (Figure 7).

Description: In short, the chain code is a way to represent a binary object by encoding only its boundary. The chain code is composed of a sequence of numbers between 0 and 7. Each number represents the transition between two consecutive boundary pixels, 0 being a step to the right, 1 a step diagonally right/up, 2 a step up, etc. In the post Measuring boundary length, I gave a little more detail about the chain code. Worth repeating here that post is the figure containing the directions associated to each code:
The chain code thus has as many elements as there are boundary pixels. Note that the position of the object is lost, the chain code encodes the shape of the object, not its location. But we only need to remember the coordinates of the first pixel in the chain to solve that. Also note, the chain code encodes a single, solid object. If the object has two disjoint parts, or has a hole, the chain code will not be able to describe the full object.-In short, the chain code is a way to represent a binary object by encoding only its boundary.
