the effects of different stages of maturity (mature green, until 20 to 40% of change in color), two treatments of cool water (5 ?c for 5' and 10 ?c for 15min.), two treatments of hot water (50 ?c for 15 min. and 55 ?c for 5 min.) ), two temperatures (10 and 14 °c) of storage vs. six time periods (0, 5, 10, 15, 20 and 25 days) on shelf life and storage time of ‘langra’ mango fruit were stud...

Human skin detection is a very popular in many applications, particularly in video surveillance. Many researchers have conducted research in this area, by producing a variety of effective methods. In this paper, research carried out by using a simple algorithm, lower cost, and high detection rate; a hybrid method for detecting human skin region that base on background subtraction and skin color...

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 ...

Melanoma is the deadliest form of skin cancer and presents a significant health care burden in many countries. In addition to ultraviolet radiation in sunlight, the main causal factor for melanoma, genetic factors also play an important role in melanoma susceptibility. Although genome-wide association studies have identified many single nucleotide polymorphisms associated with melanoma, little ...

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...

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...
