本研究是以「Harris and Beath footprinting mat」擷取足底影像，利用影像處理尋找足底輪廓與足印參數。首先，以提高對比度及平滑處理之方法對足底影像進行影像處理，再利用目標吸引平均主動輪廓模型，將初始輪廓設定於足印周圍，以取得足底影像輪廓，藉此輪廓計算出足印參數、足長及足寬。藉由足印參數可以了解足部問題，也可將足長、足寬應用在鞋楦的比對上，以找到適合此腳形的鞋子。
In this research the plantar image acquired by "Harris and Beath footprinting mat" is applied for tracing of the plantar contour and footprint parameters using image processing. In tracing of the plantar contour the contrast of the plantar image is first increased and then smoothed. The snake with the attraction and even distance energy is applied for tracing of the plantar contour by setting the initial snake curve close to the edge of the plantar contour. Moreover, the footprint parameters, foot length and foot width are further calculated. Footprint parameters can know foot problems, and foot length and foot width can be applied on shoe last so that the foot shape can find the appropriate shoes.
