Abstract: An input image of an object is prepared for presentation by removing extraneous portions such as text, logos, advertising, watermarks, and so forth. The input image is processed to determined contours of features depicted in the input image. A bounding box corresponding to each contour may be determined. Based at least in part on the areas of these bounding boxes, an image mask is created. A candidate image is determined by applying the image mask to the input image to set pixels within portions of the input image to a predetermined value, such as white. Many candidate images may be generated using different parameters, such as different thresholds for relative sizes of the areas of the bounding boxes. These candidate images may be assessed, and a candidate image is selected for later use. Instead of manual editing of the input images, the candidate images are automatically generated.
