New Real-time Endoscopy Image Processing Technology of Hemoglobin Color Enhancement

摘要

Video endoscopes play an important role in clinic practice for gastrointestine and bronchial tracts. Using these video endoscopes, a depressing type of early cancer which has recently been focused on can be identified with change in color tone such as reddening or discoloration. Some hemoglobin color enhancement processing algorithms have been developed to make this slight color tone change clear in real-time. In this paper, we will introduce a new algorithm which has been partially incorporated into a commercial endoscope system AQ-100. The basic principle of the algorithm is to adjust the RGB components based on the IHb value. Through Matlab simulation result and application feedback in clinic practice, this partially incorporated algorithm is confirmed effective in both simulation and clinic practice. Though the complete algorithm has a better effect in simulation, it still has some problems to be resolved before it can be applied into clinic practice.
