Skin Colour Detection Under Changing Lighting Conditions

Human Face Detection under Complex Lighting Conditions

This paper presents a novel method for detecting human faces in an image with complex backgrounds. The approach is based on visual information of the face from the template image and is commenced with the estimation of the face area in the given image. As the genetic algorithm is a computationally expensive process, the searching space for possible face regions is limited to possible facial fea...

Colour analysis and verification of CCTV images under different lighting conditions

Colour information is not faithfully maintained by a CCTV imaging chain. Since colour can play an important role in identifying objects it is beneficial to be able to account accurately for changes to colour introduced by components in the chain. With this information it will be possible for law enforcement agencies and others to work back along the imaging chain to extract accurate colour info...

Efficiency of Caries Detection Using Two Types of Intraoral Films under Different Processing Conditions

Introduction: The image quality as well as film speed is influenced by the film processing conditions. Different combinations of films and processing methods affect the diagnostic accu-racy. Temperature and developer exhaustion result in different image quality. The purpose of this study was to evaluate the influence of film type and processing conditions on caries detec-tion.  Material a...

Change detection from satellite images based on optimal asymmetric thresholding the difference image

As a process to detect changes in land cover by using multi-temporal satellite images, change detection is one of the practical subjects in field of remote sensing. Any progress on this issue increase the accuracy of results as well as facilitating and accelerating the analysis of multi-temporal data and reducing the cost of producing geospatial information. In this study, an unsupervised chang...
