and the second level uses the weighted directional operator.For noise restoration,the non-noisy pixels remain unchanged;the noisy pixels are restored by the double weighted vector median filtering algorithm.Experimental results show that the proposed algorithm can filter the noises effectively and ...
LULU filters are nonlinear rank selector operators which are computationally more competent and the performance of the operator is straightforward to describe. The comparison between Median and LULU filters, in this paper, is performed using two different image quality metrics which are RMSE and PSNR...
Canny edge detection is a widely used operator in image processing. With the wide application of Canny operator, its problems in noise processing, threshol... Z Lv,F Wang - International Conference on Computer Science & Management Technology 被引量: 148发表: 0年 A rank ordered filter for med...
This article proposed an image edge detection method based on the median value filter,Sobel and Canny Operator under the noise condition.First,use the median value filter to smooth the image,and then use Sobel and Ganny Operator to detect the image edge.The simulation experiment demonstrates that...
Improving BTC image compression using a fuzzy complement edge operator A simple and easy to implement technique for improving block truncation coding (BTC) is proposed. The method is based on replacement of bit block obtained ... TM Amarunnishad,VK Govindan,AT Mathew - 《Signal Processing》 被...
With characteristics of impulse noise and Gaussian noise, we propose a new denoising method to infrared image. We use Sobel operator to obtain boundary information, and determine the denoising method based on the pixel number of the peer group, denoising impulse noise and Gaussian noise with media...
