QUANTUM RENYI ENTROPY WITH APPLICATION IN IMAGE PROCESSING
Keywords:
histogram, image segmentation, quantum Renyi entropy, Image primitive, quantum state, thresholdingAbstract
Thresholding is a basic method for image segmentation. First, we plot a histogram of image to a quantum state. The quantum state represents pixel intensities, and the density matrix represents their probability distribution. Secondly, we plot a histogram of the segment image to a quantum state. The quantum state represents pixel intensities of classes. Finally, we obtain the optimal thresholding by quantum Renyi entropy which explains physical interpretation in quantum language.
