This paper presents an experimental investigation of the application of multispectral imaging in dermatology. The focus areas of this work are as follows: a) the improving the color reproduction accuracy of skin lesions, b) exploring the spectral feature of skin disease using the multispectral color enhancement technique, and c) multispectral image analysis aiming at supporting quantitative dia...

Face detection which is a challenging problem in computer vision, can be used as a major step in face recognition. The challenges of face detection in color images include illumination differences, various cameras characteristics, different ethnicities, and other distinctions. In order to detect faces in color images, skin detection can be applied to the image. Numerous methods have been utiliz...

In this paper, we propose a technique to efficiently detect human skin in color images with complex background and varying illumination conditions. The strategy consists of modeling the distribution of skin colors using a Gaussian mixture model (GMM) and segmenting the image into skin and non-skin parts, using threshold values that are computed automatically by an adaptive technique. Morphologi...

Quantification of erythema and/or pigmentation is important for in vivo assessment of skin reactions to external stimuli such as ultraviolet radiation. Measurement of lesional color is also useful for quantitative evaluation of the efficacy of therapies for skin lesions. Several types of portable optoelectronic instruments have recently become available for these purposes and have been applied ...

In processes of face detection, face tracking and gesture recognition, the skin color detection is usually a post-processing step that plays such an important role. The skin color detection can almost be viewed as a two class problem with a non-skin color pixel vs. skin color pixel classifier. In this paper, we present a classifier that was built by combining a statistical skin color model and ...

The following two studies examined the role of skin color on children’s biological and nonbiological judgments. Study 1 examined preschoolers, first graders, third graders, fifth graders and adults’ reasoning about the impact of skin color on the contraction of common contagious illnesses. Study 2 assessed children’s and adults’ impact of skin color on positive and negative social behaviors. Re...

To eliminate the color appearance variation of the images acquired under the various lighting conditions, we have developed a simple four colored chart (Skin chart) for the color calibration of the human skin images based on the features of the human skin color. The color calibration with the Skin chart worked better than that with a standard color chart. A conventionally obtained photo-image o...

Background: Melanin pigmentation of the gingiva occurs in allethnicities. Excessive pigmentation is an esthetic concern thathas increased awareness about depigmentation procedures. Thepurpose of the present study was to correlate the skin color andgender with the intensity and distribution of gingival melaninpigmentation in a group of South Indians for treatment strategies.Method: Two hundred m...

The applications of skin color recognition are extended in utilizations both in content based analysis and human computer interactions. Therefore, achieving a useful method for segment the skinlike pixels can help the presented problems. In this paper a hybrid PSOGSA -ANN is proposed as a new training method for Feed forward Neural Networks (FNNs) in order to investigate a high efficiency for s...

The content of this paper is the proposal of two techniques for the modeling of skin color in images using a combination of spaces of colors HSV with YCbCr and HSV with CIELab. To determine the intervals of pixels nonskin color uses the components H and S, on the other hand, the intervals of pixels skin color uses the components Cb, Cr, a and b. There are compared the results of the technique H...
