This paper reviews about the different algorithms used for image enhancement. Image
processing is a process of matching and overlay more than one image of any scene. This is …

Depth information is useful in many image processing applications. However, since taking a
picture is a process of projection of a 3D scene onto a 2D imaging sensor, the depth …

Feature points loss and images mismatch in the variation of light intensity, weak texture and
large angle rotation for the feature points extraction of ORB-SLAM2 are severe. To deal with …

Depth maps play an important role in the representation of 3D information. They are often
simultaneously acquired with color images; however, their resolution is significantly lower …

A method for sharpening of 3D volume images has been developed. The idea of the
proposed algorithm is to transform the 3D neighborhood of the edge so that the neighboring …

Numerous algorithms exist for the problem of deconvolution of blurred images. But due to ill-
posed nature of deconvolution, many images still remain blurry after deblurring. An edge …

A method to improve the results of image enhancement is proposed. The idea of the method
is to warp pixel grid by moving pixels towards the nearest image edges. It makes edges …

A method of enhancing the 3D structure of fundus images has been developed. It is based
on grid warping techniques and ensures both denoising and vessel sharpening of fundus …

General methods of image processing, analysis and enhancement and their biomedical
applications developed by the scientific school of the Laboratory of Mathematical Methods of …

The development of image sharpening algorithms is currently one of the most important
problems in image processing. This paper presents a parallel implementation of a pixel grid …
