Abstract

Abstract A method and computer program/system for cropping a digital image includes inputting a belief map of a photographic image, (a belief value at a location in the belief map indicates an importance of a photographic subject at the same location in the photographic image), selecting a zoom factor and a crop window, clustering regions of the belief map to identify background portions, secondary portions and main portions, positioning the crop window such that the crop window is centered around a main portion having a highest belief value, moving the crop window such that the crop window is included completely within the image, moving the crop window such that a sum of belief values is at a maximum, and cropping the image according to the crop window.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 85 words
A method of cropping an image comprising: inputting a belief map of a photographic image, said belief map comprising a plurality of belief values, each belief value at each location in said belief map indicating an importance of a photographic subject at said location wherein a photographic subject having a highest belief value comprises a main subject; selecting a crop window; positioning said crop window such that said crop window is centered around said main subject; and cropping said image according to said crop window.
Claim 2
Dependent Claim 21 words
The method in claim 1, further comprising selecting a zoom factor in order to determine a size of said crop window.
Claim 3
Dependent Claim 19 words
The method in claim 2, wherein said zoom factor is selected according to a size of said main subject.
Claim 4
Independent Claim 15 words
The method in claim1, further comprising clustering regions of said belief map into belief categories.
Claim 5
Dependent Claim 25 words
The method in claim 4, wherein said clustering includes setting portions of said belief map having a lowest belief value to a zero belief value.
Claim 6
Dependent Claim 21 words
The method in claim 1, further comprising moving said crop window such that said crop window is completely within said image.
Claim 7
Dependent Claim 26 words
The method in claim 1, further comprising moving said crop window such that a sum of belief values of said crop window is at a maximum.
Claim 8
Dependent Claim 22 words
The method in claim 1, further comprising moving said crop window such that said crop window includes all of said main subject.
Claim 9
Dependent Claim 19 words
The method in claim 1, further comprising moving said crop window to include a buffer around said main subject.
Claim 10
Dependent Claim 27 words
The method in claim 1, further comprising repeating said moving processes with a rotated image and determining if said rotated image produces a higher sum of beliefs.
Claim 11
Dependent Claim 31 words
The method in claim 1, further comprising repeating said positioning process and said moving processes with a rotated image and determining if said rotated image produces a higher sum of beliefs.
Claim 12
Dependent Claim 28 words
The method in claim 1, further comprising repeating said processes with a second crop window and determining if said second crop window produces a higher sum of beliefs.
