This paper gives an overview of scale-space and image enhancement techniques which are
based on parabolic partial differential equations in divergence form. In the nonlinear setting …

We develop an efficient general-purpose no-reference (NR) image quality assessment (IQA)
model that utilizes local spatial and spectral entropy features on distorted images. Using a 2 …

Partial differential equations (PDEs) have led to an entire new field in image processing and
computer vision. Hundreds of publications have appeared in the last decade, and PDE …

Many approaches have been proposed to solve the problem of finding the optic flow field of
an image sequence. Three major classes of optic flow computation techniques can …

A method is proposed to enhance vascular structures within the framework of scale space
theory. We combine a smooth vessel filter which is based on a geometrical analysis of the …

With the rapid proliferation of virtual reality (VR) technologies, the usage of VR in
multimedia, education, and social media platforms has increased due to realistic and …

This paper presents an application of fuzzy set theory for classification of individual tree
crowns into species groups, in high spatial resolution colour infrared aerial photographs. In …

This article investigates Renyi's (1976) generalized entropies under linear and nonlinear
scale-space evolutions of images. Scale-spaces are useful computer vision concepts for …

Light field image quality assessment (LF-IQA) plays a significant role due to its guidance to
Light Field (LF) contents acquisition, processing and application. The LF can be represented …

Images can be broadly classified into two types: isotropic and anisotropic. Isotropic images
contain largely rounded objects while anisotropics are made of flow-like structures …
