去噪滤波技术是数字图像处理中的一个重要内容,是计算机视觉技术、模式识别、图像数据分析的基础,因而受到广泛的研究;并在人脸识别、表情识别、遥感成像等领域获得广泛的应用。通过对多种去噪滤波算法进行比较,选定了一种改进的二维中值滤波快速算法将其应用到表情识别中,得到较好效果。
去譟濾波技術是數字圖像處理中的一箇重要內容,是計算機視覺技術、模式識彆、圖像數據分析的基礎,因而受到廣汎的研究;併在人臉識彆、錶情識彆、遙感成像等領域穫得廣汎的應用。通過對多種去譟濾波算法進行比較,選定瞭一種改進的二維中值濾波快速算法將其應用到錶情識彆中,得到較好效果。

Denoising and fiher technology is a main content of image processing technology, and it is the base of computer vision technique, pattern recognition,analysis of image data, which has been studied extensively and widely applicated in facial recognition, expression recognition, remote sensing imaging and so on . In this paper, it was proved that an improved fast 2-D media filter algorithm had potential to improve the expression recognition by a comparison between several denoising and filtering algorithms.
