METHOD AND APPARATUS OF DIFFERENTIATING BETWEEN A BACKGROUND AND A REGION OF INTEREST

摘要

The present invention relates to a method for differentiating an interest region, comprising the steps of detecting strength for each pixel of interest region image acquired by a wavelength, corresponding to each pixel an index corresponding to an image having the largest strength corresponding to each pixel, generating the signal weight corresponding to each pixel considering the wavelength that the interest region absorbs, and applying the generated signal weight for each pixel to each pixel of image acquired by the wavelength that the interest region absorbs at most to generate the image of which background is differentiated, wherein an optical sound image acquired while varying optical wavelengths is analyzed to give an index to the image, thereby differentiating background signals from desired signals.
