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.

Dependent claims

A system comprising:

at least one memory storing computer-executable instructions;
and
at least one processor in communication with the at least one memory, the at least one processor executes the computer-executable instructions to:
receive an input image depicting an object;
determine a preprocessed image by adding a boundary to the input image;
determine a first contour of the preprocessed image;
determine a first area of the first contour;
determine a second contour of the preprocessed image;
determine a second area of the second contour;
determine a third contour of the preprocessed image;
determine a third area of the third contour;
determine the second area is less than a first threshold percentage of the first area;
determine the third area is less than the first threshold percentage of the first area;
determine a first image mask based on the second contour and the third contour;
determine a first candidate image by applying the first image mask to the preprocessed image;
determine the second area is greater than a second threshold percentage of the first area;
determine the third area is less than the second threshold percentage of the first area;
determine a second image mask based on the third contour;
determine a second candidate image by applying the second image mask to the preprocessed image;
determine first output data comprising instructions to present the first candidate image and the second candidate image;
determine selection data indicative the first candidate image;
store the first candidate image, wherein the first candidate image is associated with the object;
and
determine second output data comprising instructions to present the first candidate image.
