A novel design of urine test strip with spatially adjacent reference color chart

Abstract

Urine test strips are frequently used to analyze health status of patients due to its simplicity. However, in order to analyze the urine test strip, expensive hardware is required to match changed colors. In order to solve the problem, a novel design of the urine test strip is proposed. By using the proposed design, extra equipment is not required and the proposed design is robust against illumination changes. Through a series of experiments, the proposed design gives a correct decision in general, dim, and flash light condition.
