Wavelet multiresolution analysis allows us to detect edges at different scales
also to obtain other important aspects of the extracted edges. However
due to the usual two-dimensional tensor product
wavelet transform is not optimal for representing images. The main problem in edge detection using wavelet transform is that it can only capture point-singularities
and the extracted edges are not continuous. In order to solve that problem
we propose a new image edge detection method based on the contourlet transform. The directional multiresolution representation Contourlet takes advantages of the intrinsic geometrical structure of images
and is appropriate for the analysis of the image edges. Using the modulus maxima detection
an image edge detection method based on contourlet transform is proposed. To suppress the image noise effect on edge detection
the scale multiplication in contourlet domain is also proposed. Through real images experiments
the proposed edge detection method's performance for the extracted edges is analyzed and compared with other two edge detection methods. The experiment result proves that the proposed edge detection method improves over wavelet-based techniques and Canny detector
and also works well for noisy images. 2010 IEEE.

A wavelet-based approach of aerial blurred image restoration is proposed in this article. Image motion is inevitable in photographing for aerospace camera. Though some Image Motion Compensation(IMC) schemes are applied in aerial imaging system
the ultimate image will be blurred in certain extent for the existence of IMC residual error
while the forward image motion is the key element among all image motions which lead to image blurring. First the course of blurring caused by forward image motion is expressed using wavelet transform
and a multiresolution sparse matrix representation of the degeneration model is obtained according to the wavelet transform. Subsequently a regularizing restoration algorithm is deduced from it
and which can smoothly restraint the processed result efficiently. In the end the proposed approach is tested in MATLAB. The blurred image is restored using above-mentioned wavelet algorithm
conventional contrary filter and Wiener filter algorithm separately. The conclusion that the wavelet-based restoration algorithm is superior to other two approaches is obtained by comparing the restored image's value of mean gradient. The calculating quantity of the wavelet-based blurred image restoration approach isn't large and it has good practicability in the field of image interpretation and aerial survey or drawing.
