Diagnosis of tongue diseases using fractal concept is the central theme of experimental and theoretical investigation. The variation of intensity and texture complexity of tongue including patches on the tongue are calculated by fractal dimension methods. Box Counting Method and radial distance measure are employed in identifying the shape of the tongue. Conventional Box Counting Method is compared with Sobel improved Box Counting Method. Lacunarity is used to analyze the texture of tongue. Analysis of the shape of tongue and evaluation of its dimension using Mathematical techniques saves time and increases the quality of diagnosis.
