Detection of an object in an image

A system for identifying a portion of a digital image corresponding to an object, the system comprising:

• at least one computing device operable to carry out a method comprising:
• deriving an initial object indication mask based on pixel-wise differences between a first digital image and a second digital image, at least one of which includes the object;
• performing an edge finding operation on both the first and second digital images, wherein the edge finding operation includes marking added edges;
• generating a plurality of straight linear runs of pixels across an image containing the object, wherein each of the plurality of straight linear runs starts and ends on an added edge and is contained within the initial object indication mask;
• and
• forming a final object indication mask by retaining only pixels that are part of at least one of the plurality of straight linear runs.

A computer-readable storage medium containing a program product, which when executed, is operable to identify a portion of a digital image corresponding to an object, by performing a method comprising:

• deriving an initial object indication mask based on pixel-wise differences between a first digital image and a second digital image, at least one of which includes the object;
• performing an edge finding operation on both the first and second digital images, wherein the edge finding operation includes marking added edges;
• generating a plurality of straight linear runs of pixels across an image containing the object, wherein each of the plurality of straight linear runs starts and ends on an added edge and is contained within the initial object indication mask;
• and
• forming a final object indication mask by retaining only pixels that are part of at least one of the plurality of straight linear runs.

A method for deploying an application for detecting an object in a digital image, comprising:

• providing a computer infrastructure being operable to:
• derive an initial object indication mask based on pixel-wise differences between a first digital image and a second digital image, at least one of which includes the object;
• perform an edge finding operation on both the first and second digital images, wherein the edge finding operation includes marking added edges;
• generate a plurality of straight linear runs of pixels across an image containing the object, wherein each of the plurality of straight linear runs starts and ends on an added edge and is contained within the initial object indication mask;
• and
• form a final object indication mask by retaining only pixels that are part of at least one of the plurality of straight linear runs.
