| 中文摘要: |
| 针对机载仪表视频图像存在边缘模糊,字符不清,传统算法难于识别的缺点,提出了一种基于梯度锐化的图像边缘检测的优化算法.实验表明,该优化算法能较好地解决传统算法所造成的图像变暗的问题.在不破坏原始背景的情况下,满足对图像的边缘增强及根据需要增强边缘的需求. |
| 英文摘要: |
| A optimum algorithm based on gradient sharpening about edge detection of image is proposed according to the shortcoming of the conventional algorithm unable to recognize the blurred edge,unclear character in the image of instrument on board.The experiment results show the optimum algorithm can solve preferably the problem which the image turned dark by traditional algorithm.The effect of the edge enhancement to the image is maintained in the condition not to destroy the original background. |
