某些特殊涂料可以允许特定波段的红外光透过，而阻止可见光透过，因此可以利用这个特点，用红外成像来检测和判断以实现防伪防篡改的目的。由于从红外摄像机中提取到的图像在转换成灰度图像后存在噪声、边缘模糊等缺陷，需进行图像增强才能提高后续图像处理的精确度。此外，在雨雪天、雾霾天气中采集到的红外图像也会出现模糊等问题。运用锐化滤波法，通过微分计算和处理，可使图像的边缘信息突出，便于人眼和机器的识别，能实现防伪识别和处理。
某些特殊塗料可以允許特定波段的紅外光透過，而阻止可見光透過，因此可以利用這箇特點，用紅外成像來檢測和判斷以實現防偽防篡改的目的。由于從紅外攝像機中提取到的圖像在轉換成灰度圖像後存在譟聲、邊緣模糊等缺陷，需進行圖像增彊纔能提高後續圖像處理的精確度。此外，在雨雪天、霧霾天氣中採集到的紅外圖像也會齣現模糊等問題。運用銳化濾波法，通過微分計算和處理，可使圖像的邊緣信息突齣，便于人眼和機器的識彆，能實現防偽識彆和處理。

Some special coatings can allow specific ban infrared light through and absorb the visible light. Uses this feature, combining with infrared imaging to detect, judge and realize the purpose of anti-counterfeiting tamper-proof. But there are some defects existing in the gray con-verted images which extracted from infrared cameras, like noise, edge blur and so on. In order to improve the accuracy of the subsequent image processing, image enhancement processing is needed. In addition, infrared images collected from the rainy, snowy day and foggy weather also can appear fuzzy. The sharpen filter, uses differential calculation and processing, makes the edge information of image out-standing. Both human and machine can have a good recognition of it. Realizes anti-counterfeiting recognition and processing.
