Abstract
© 2014 IEEE. There have been many techniques for demonstrating different Pedobarograph systems to measure a foot pressure that can be used for a clinical tool. This tool can aid a surgeon's decision making. This paper presents development of optical sensor device for acquisition of Pedobarograph through the use of measuring the pressure foot which is relative to the weight. The optical sensor is utilized in terms of low cost and easy available while electronic matrix force plate (Tekscan®) is high cost and imported from overseas. For the proposed methods, weighted (or inputted) images from the pressure foot are captured from illuminated. Such weighted images are computed by image processing e.g Gaussian filtering, canny edge detection, region of interest, illuminate slicing. Then, statistical analysis using ANOVA testing and correlation technique will be used to verify the resulting of Pedobarograph between optical sensor and Tekscan® (electronic commercial product). The samples is 58 feet from 28 normal Subjects. The results show that F-statistics is approximately at 1,855.632, Significant (Sig.) value is equal to 0.001 (P<0.05) and correlation coefficient is 0.764 indicating a strong relationship. This means that the optical sensor can be used for substituting the Tekscan®.
