A well-known method for generating computer art is based on the paradigm of user-guided evolution, a method whereby "artists" interactively search through populations of images in order to select, and subsequently breed, those images which show aesthetic promise. This can be a time consuming endeavor, lacking well-defined principles for controlling evolution and for obtaining images with desire...

Color constancy algorithms are used for making illuminant independent images. Illuminant independency is achieved in most of algorithms by uniform light source assumption. But this condition may violate in most of real world images which introduces performance failure in computer vision applications like object tracking and object recognition. Local color correction for up to two light sources ...

We address the need for robust detection of obstructed human features in complex environments, with a focus on intelligent surgical UIs. In our setup, real-time detection is used to find features without the help of local (spatial or temporal) information. Such a detector is used to validate, correct or reject the output of the visual feature tracking, which is locally more robust, but drifts o...

An authentication scheme that uses rehashing and secret sharing methods to verify the reality of a color image’s content is proposed in this paper. First, the proposed scheme uses Shamir’s secret sharing method to share image features. Second, the proposed scheme innovatively utilizes the rehashing method to overcome easy collisions of the random numbers to enhance the effectiveness against att...

Modifying the colors of an image is a fundamental editing task with a wide range of methods available. Manipulating multiple images to share similar colors is more challenging, with limited tools available. Methods such as color transfer are effective in making an image share similar colors with a target image; however, color transfer is not suitable for modifying multiple images. Approaches fo...

Elimination of illumination color in color images is essential for various fields in computer vision. Many methods have been proposed to solve it, however there are few methods employing varying illumination as a constraint. We found Finlayson et al. ’s method [10] applicable for natural images, and extended it by making the reference illumination variable. To evaluate our method, we have condu...

It is paradoxical that individuals with mental retardation are disproportionately represented in the criminal justice system, suggesting a greater proportion of false positives, while at the same time there is concern regarding a potential motivation for individuals without mental retardation to simulate such a condition for the purpose of avoiding the death penalty, a concern for false negativ...

Image segmentation is a fundamental approach in the field of image processing and based on user’s application .This paper propose an original and simple segmentation strategy based on the EM approach that resolves many informatics problems about hyperspectral images which are observed by airborne sensors. In a first step, to simplify the input color textured image into a color image without tex...

Introduction: The growing demand for esthetic dental procedures has resulted in the increased development of new restorative composite resins. The success of composite resin restorations depends on their color stability over time. The present study aimed to evaluate the effects of 0.2% chlorhexidine (CHX) and re-polishing on the color stability of nanofilled composite re...

The self-organizing map (SOM) is widely used as a data visualization method in various engineering applications. It performs a non-linear mapping from a high-dimensional data space to a lower dimensional visualization space. In this paper, a simple method for visualizing the cluster structure of SOM model vectors is presented. The method may be used to produce tree-like visualizations, but the ...
