Robotic Arm Control Algorithm Based on Stereo Vision Using RoboRealm Vision

open access: yesAdvances in Electrical and Computer Engineering, 2015
The goal of this paper is to present a stereo computer vision algorithm intended to control a robotic arm. Specific points on the robot joints are marked and recognized in the software. Using a dedicated set of mathematic equations, the movement of the

Experimental Analysis for Modeling Color of Halftone Images

open access: yes, 2015
Reflectance models such as the monochrome Murray–Davies (MD) and the Neugebauer color equations make inaccurate predictions owing to changes in reflectance or tristimulus values (TSVs) of halftone dots and the paper between the dots. In this paper, we characterize the change of micro-TSVs as a function of printed area in spectral halftone image by a ...

Novel chromaticity similarity based color texture descriptor for digital pathology image analysis. [PDF]

open access: yesPLoS ONE, 2018
Pathology images are color in nature due to the use of chemical staining in biopsy examination. Aware of the high color diagnosticity in pathology images, this work introduces a compact rotation-invariant texture descriptor, named quantized diagnostic ...

Cluster Oriented Image Retrieval System with Context Based Color Feature Subspace Selection [PDF]

open access: yes, 2010
This paper presents a cluster oriented image retrieval system with context recognition mechanism for selection subspaces of color features. Our idea to implement a context in the image retrieval system is how to recognize the most important features in ...

A morphological gradient approach to color edge detection [PDF]

open access: yes, 2006
A new color edge detector based on vector differences is proposed. The basic technique gives as its output the maximum distance between the vectors within a mask.

A Brief Analysis of iColoriT for Interactive Image Colorization

open access: yesImage Processing On Line
This paper briefly describes and analyzes iColoriT, a hybrid colorization method based on a Vision Transformer that propagates user hints to relevant regions of a grayscale image while using color priors learned from a large image dataset. This approach gives users more control over color inference and shows a quick way to achieve results.

Exposing image forgery through detecting contrast enhancement [PDF]

open access: yes, 2013
In this paper, a novel forensic method of exposing cut-and-paste image forgery through detecting contrast enhancement is proposed. We reveal the inter-channel correlation introduced by color image interpolation, and show how a linear or nonlinear ...

Direct kernel biased discriminant analysis: a new content-based image retrieval relevance feedback algorithm [PDF]

open access: yes, 2006
In recent years, a variety of relevance feedback (RF) schemes have been developed to improve the performance of content-based image retrieval (CBIR). Given user feedback information, the key to a RF scheme is how to select a subset of image features to ...
