This can be seen in the healing process of a bruise, where various colour changes indicate the degradation of haemoglobin and release of carbon monoxide. 这能在撞伤的愈合过程中观察到,各种颜色的变化显示了血红素的降解和CO的释放。
Image enhancement is able to employ homomorphic filter and colour correction to enhance the objects in the image and correct the colour degradation. 图像增强算法可以利用同态滤波器来增强图像中的物体,并使用色彩校正算法处理图像中衰减的颜色。
