Skin Lesion Analysis Using Digital Imaging Techniques

Visual inspection of skin lesion may be time consuming and is prone to
inaccuracy. Conventionally, dennatologist has to visually inspect and manually
calculate the percentage of affected area on patient's body. Though the estimation
is highly subjective, therefore a computerized system of detecting and calculating
affected area will be very helpful. This report presents a computer vision method
for analysis of lesion area. The most crucial part of this work is segmentation. In
this paper, we present three methods of segmenting lesion area (represented as
colored patches) which are !.segmentation in HSI color space, 2. segmentation in
ROB color space and 3. segmentation in quantized ROB color space. The result of
three methods will then be compared to select the method that yield the best
segmentation result.
