Algorithm for pre-processing chest-x-ray using multi-level enhancement operation
Savitha S.K, N C Naveen · 2016
Accuracy in diagnostics of life-threatening disease based on chest x-ray images is an atmost importance in healthcare sector, where medical image processing has already played a contributory role from more than a decade. In this regards, image enhancement plays a critical role in exposing more information to the foreground image of clinical importance. We have reviewed the most existing system pertaining to chest image enhancement and found that more enhancements could be done to enhance the signal quality. Therefore, we present a sophisticated algorithm that performs multiple operations for enhancing the chest x-rays. The proposed paper introduces techniques for enhancing chest x-rays using non-linear enhancement, primary enhancement, secondary enhancement algorithms on JSRT database. The proposed system shows better quality of enhanced region in comparison to the most frequently adopted techniques for medical image enhancement.
