Robust Visual Segmentation using RCrR Plane and Mahalanobis Distance
In this paper a robust algorithm against illumination changes for skin detection in images is proposed. A database with 50 controlled condition images and 50 without controlled conditions of people in frontal position showing face, hands and arms was used. Five algorithms to perform color correction...

A database with 50 controlled condition images and 50 without controlled conditions of people in frontal position showing face, hands and arms was used. Five algorithms to perform color correction are evaluated: Simple Correction with Green Channel, Color Channel Compression, Color Channel Expansion, Fixed Reference and Gamma Correction. And four algorithms for segmentation are evaluated as well: RGB Skin Color, Reference Histogram, Euclidean Distance and Mahalanobis Distance. The proposed algorithm uses the Fixed Reference method together with Gamma Correction for color correction and performs the skin segmentation based on an RCrR color plane, found by making the transformation of the images using RGB and YCbCr spaces, finally Mahalanobis Distance is used.

Se evalúan 5 algoritmos para realizar corrección de color los cuales son: Corrección sencilla con canal verde, Compresión canal de color, Expansión canal de color, Referencia fija, Corrección Gamma. Se evalúan 4 algoritmos para segmentación los cuales son: Color de piel en RGB, Referencia de Histograma, Distancia Euclidiana y Distancia de Mahalanobis. El algoritmo propuesto utiliza el método referencia fija unido al algoritmo de corrección gamma para corrección de color y realiza segmentación de la piel a partir de un plano de color RCrR, encontrado de la transformación de las imágenes utilizando los espacios RGB y YCbCr, finalmente utiliza la distancia de Mahalanobis. Como resultado se obtiene un valor promedio de sensibilidad igual 99.36% y de especificidad igual 84.31%.application/pdfspaUniversidad Antonio Nariñohttp://revistas.uan.edu.co/index.php/ingeuan/article/view/389/3282346-14462145-0935INGE@UAN - TENDENCIAS EN LA INGENIERÍA; Vol. 5 Núm. 9 (2014)Faded photo correctiongray world assumptiongamma correctionilluminationskin colorsegmentationeuclidean distancemahalanobis distancehistogramCorrección foto descoloridaSuposición de mundo grisCorrección gammailuminaciónsegmentación color de pielDistancia EuclidianaDistancia MahalanobisHistogramaRobust Visual Segmentation using RCrR Plane and Mahalanobis DistanceSegmentación Visual Robusta utilizando el Plano RCrR y la Distancia de Mahalanobisinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85123456789/3952oai:repositorio.uan.edu.co:123456789/39522024-10-09 23:03:10.515https://creativecommons.org/licenses/by-nc-sa/4.0/Acceso abiertometadata.onlyhttps://repositorio.uan.edu.coRepositorio Institucional UANalertas.repositorio@uan.edu.co |
