Direct Noise-Resistant Edge Detection with Edge-Sensitive Single-Pixel Imaging Modulation
Intelligent Computing, 2023 The majority of edge detection methods are applied after the capture of object photos. Thus, edge detection quality suffers when disturbances occur during imaging. This work proposes an effective edge detection technique for single-pixel imaging (SI).

Directional interpolation of noisy images [PDF]
2008 15th IEEE International Conference on Image Processing, 2008 Most of the existing image interpolation schemes assume that the image is noise free. This assumption is invalid in practice because noise will be corrupted in the image acquisition process. The conventional way is to denoise the image first and then interpolate the denoised image.

Image Denoising with Directional Bases [PDF]
2007 IEEE International Conference on Image Processing, 2007 Directional information is an important component of both natural and synthetic images, and it is exploited in many image processing applications. Directional basis analysis is used to capture significant structural information. This paper presents an empirical study of image denoising with directional bases. We consider two distinct approaches.

Near-Field 3D Sparse SAR Direct Imaging with Irregular Samples
Remote Sensing, 2022 Sparse imaging is widely used in synthetic aperture radar (SAR) imaging. Compared with the traditional matched filtering (MF) methods, sparse SAR imaging can directly image the scattered points of a target and effectively reduce the sidelobes and clutter
