Underwater resource development is more and more important, but some underwater operations, such as scientific exploration and construction work depending on underwater observation, are with visual difficulties because of the turbid water. To improve ...

Image super-resolution (SR) is of great significance in image processing field by providing an alternative approach to overcome the resolution limitations of devices. Many sparse representation based methods use a single pair of dictionaries for image ...

Computer vision technology is widely used based on its massive and correct data set, of which the bounding box labeling is a common method. Aimed at a large number of original image data set produced by virtual simulation, we proposed an automatic pixel-...

Aiming at the problem that the existing image contour extraction algorithm can't be accurate to the pixel level, this paper proposes a cable contour extraction method based on candidate point merge search. The algorithm is divided into three steps: ...

To improve the detection level and performance of designed infrared motion analysis system, a combined scheme is proposed to get long-term tracklet for flying small objects: 1) point object is efficiently detected via a fast background extraction, and ...

This paper investigates the issue of vision orientation for unknown spacecraft in orbit-capture, upon which a fast and highly accurate pose measurement method based on improved coordinate system correction by weighted principal component analysis (PCA) ...

The appearance of outdoor images is easily affected by natural phenomena such as fog and dust, which reduces contrast and color distortion. Video dehazing has a wide range of real-time applications, but the challenges mainly come from large amount of ...

The purpose of this paper is two-fold. First, we develop a regularized and accelerated version of Ahmed's multi-channel blind deconvolution algorithm based on low-rank matrix recovery. Second, we apply the developed algorithm to motion-less super-...

In 3D animation and visual effects productions, a typical method of reproducing realistic real-world lighting and ambient color reflections onto 3D elements is to use HDRI (High Dynamic Range Imaging) maps captured on-set and rendered expensively by ...
