函数说明 

LEDSensitivity := 0.6
LEDMinSize := 35
LEDMaxSize := 400
LEDMethod := 1
LEDType :=1
LED (Image, LEDDefectTrans, LEDSensitivity, LEDMethod, LEDType, LEDMinSize, LEDMaxSize, R, G, B, C, I, E, Va, error)

        通过图像分解、色彩空间转换、区域处理、形状分析和颜色亮度计算等步骤，实现了对LED缺陷的精确识别。代码首先进行图像的粗定位和精确定位，然后根据不同的方法计算LED缺陷的颜色和亮度信息。
