Augmented Reality Occlusion

An augmented reality processing system for generating for generating an augmented reality image from first and second images, wherein at least a portion of at least one of the first and the second image is captured from a real scene, the augmented reality processing system comprising:

• a confidence identification module arranged to identify a confidence region in which a confident determination as to which of the first and second image to render in that region of the augmented reality image can be made;
• an uncertainty identification module arranged to identify an uncertainty region in which it is uncertain as to which of the first and second image to render in that region of the augmented reality image;
• a blend module arranged to determine at least one blending factor value in the uncertainty region based upon a similarity between a first colour value in the uncertainty region and at least one second colour value in the confidence region;
• and
• an image generation module arranged to generate an augmented reality image by combining, in the uncertainty region, the first and second images using the at least one blending factor value.

A computer readable storage medium having stored thereon a computer readable description of an integrated circuit that, when processed in an integrated circuit manufacturing system, causes the integrated circuit manufacturing system to manufacture an augmented reality processing system for generating for generating an augmented reality image from first and second images, wherein at least a portion of at least one of the first and the second image is captured from a real scene, the augmented reality processing system comprising:

• a confidence identification module arranged to identify a confidence region in which a confident determination as to which of the first and second image to render in that region of the augmented reality image can be made;
• an uncertainty identification module arranged to identify an uncertainty region in which it is uncertain as to which of the first and second image to render in that region of the augmented reality image;
• a blend module arranged to determine at least one blending factor value in the uncertainty region based upon a similarity between a first colour value in the uncertainty region and at least one second colour value in the confidence region;
• and
• an image generation module arranged to generate an augmented reality image by combining, in the uncertainty region, the first and second images using the at least one blending factor value.
