Diabetes is a grave metabolic disease described by high glucose levels. The feet of pa-tients with diabetes are at the danger of a variety of neurotic results including peripheral vascular infection, disfigurement, ulceration, and necrosis (infection caused by localized death of living cells or tissue) leading to amputation. The way to deal with the diabetic foot is anticipation and early location. Sadly, currently health provider’s focus on re-sponsive diabetes mind and the accessibility of lacking subjective demonstrative screen-ing methodology makes doctors miss the finding of a few patients.

The main objective is that diabetic foot demonstrates basic neuropathic and vascular symptoms. When a foot patient is inactive, the thermal recuperation will be much slow-er. This thermal response speed can be used as a quantitative measure for the study of diabetic foot condition.

In our study, thermal recovery of the foot following cold pressure is discovered using a thermal camera. The captured thermal image is then analysed, and the temperature re-covery at each point on the foot is extracted and calibrated using a thermal control ap-pears, and the precarious regions are recognized. In addition, LED-based spectral imag-ing is tested to estimate oxygen saturation in the foot.

In this subject, we show our examinations on the following parts of the implementation of medical application analytic system based on: measurement protocols, thermal image segmentation, new techniques to perform model analysis of gathered images, and our preliminary discoveries focused on small scale clinical investigation of some patients, which demonstrate the potential of the diagnostic system.
