Patent ID: 8131054

Claim:
A method for differentiating lesions from surrounding tissue comprising: applying acetic acid to epithelial cells to produce acetowhite regions; taking at least one post acetic acid image of said acetowhite regions using a digital imager; detecting a cervix region, an os region and a columnar epithelium region in an anatomic region of interest in said post acetic acid image, wherein said columnar epithelium region is detected using only color information; extracting texture information from a first portion of said anatomic region of interest in said post acetic acid image that excludes said os region and said columnar epithelium region, to define a texture region; extracting color information from a second portion of said anatomic region of interest in said post acetic acid image that excludes said os region, said columnar epithelium region, and said texture region, to define a color region; and combining said texture region and said color region to create candidate acetowhite regions.
