Background for study • Skin diseases are important health problems which also impair the quality of life (Kurpiewska et al., 2011) • The lesions seen in skin diseases may vary in severity from minor localized patches to complete body coverage (Ho, 2010) • Diagnosis mainly depends on the experience of the clinician • Human judgement may have discrepancies in quantification of information gathering, accuracy, reproducibility of data (Broek et al., 2011) • Biopsy for histopathology is, invasive test and also time consuming (Manocha et al., 2011)
Introduction • Image analysis is the extraction of relevant information from images using the digital image processing techniques (Gonzalez and Woods, 2002) • It is very closely related to the medical imaging field, medical image analysis focuses on the computational analysis • The methods can be grouped into several categories: image acquisition, image segmentation, feature extraction (Gonzalez and Woods, 2002) • Machine learning draws results from artificial intelligence, probability and statistics, control theory (Mitchell, 1997)

Table 2. National scenario of the study. Literature survey
Rationale of study • The available information related to current work is scarce • Currently 15 working online databases are available worldwide (Dermnet, 1998; Hardin.MD, 2010) and no authentic online databases are available from India • Existing databases has limitations like, updation, diseased image metadata, user registration, prognosis tool • Earlier disease classification tools, classified specific disease from normal skin and other 6 related skin diseases
Relevance of study • Teledermatology services will be easily instituted for patients with skin ailments • Assist the dermatologists in disease prognosis
Aim of study • To develop a teledermatology application including database and software to compare and classify various skin diseases
Objectives of study • To collect the diseased image and create a database • Use the database for teledermatologyapplication • To develop a classification tool for skin diseases
Materials • A camera to collect the images (Canon 1200D with 18-55 and 50mm lens) • A high performance computer (1TB HDD, 8GB RAM, i7 processor, 2GB graphic card, 18.5” TFT) for programming • MATLAB tool to develop the machine learning based diagnosis software • Server to host teledermatology application
Methods • Data (image) collection • White or dark background using digital camera • Sample size – 1000 images (Arfin et al., 2012, Yusof et al., 2011) • Sample – Normal skin, Diseased lesion (Plaque psoriasis, Chronic eczema, Lichen planus, Pityriasisrosea) • Sample source – Department of skin and VD, Yenepoya medical college, YenepoyaUniversity • Naming each image with a unique code and create a database in MS Excel
Methods • Teledermatology application • Creating application backend by collected information • Backend – MySQL • Developing graphical interface for user • Frontend – PHP, Java Scripts • Diagnosis software • Pre-processing – Removing unwanted information from image • Hair removing, cropping • Feature extraction – Extracting useful regions from image • Color and texture features
Methods • Classification – Making a decision based on extracted feature • Statistical analysis • Sensitivity, specificity and accuracy
