Image Processing Method and Apparatus
First Claim
1. An image processing method comprising:
- acquiring a main image of a scene and one or more further images approximately of a same scene within a time period including said acquiring of said main image;
determining one or more regions of interest in said main image and said one or more further images;
analyzing said one or more regions of interest; and
determining to initiate a further action based on said analyzing of at least one region of interest, includingapplying a model to said at least one region of interest;
analyzing one or more parameters of said model for said at least one region of interest to provide an indication that a characteristic of said at least one region of interest has at least a threshold value;
segmenting from said main image or said one or more further images, or both, said at least one region of interest;
comparing said at least one region of interest with at least one stored profile region also having at least said threshold value of said characteristic; and
initiating said further action based on said analyzing of said at least one region of interest and on said comparing.

Abstract
An image processing technique includes acquiring a main image of a scene and determining one or more facial regions in the main image. The facial regions are analysed to determine if any of the facial regions includes a defect. A sequence of relatively low resolution images nominally of the same scene is also acquired. One or more sets of low resolution facial regions in the sequence of low resolution images are determined and analysed for defects. Defect free facial regions of a set are combined to provide a high quality defect free facial region. At least a portion of any defective facial regions of the main image are corrected with image information from a corresponding high quality defect free facial region.

8. An image acquisition and processing apparatus, comprising:
-
a lens and image sensor for acquiring a main image of a scene and one or more further images approximately of a same scene within a time period including said acquiring of said main image; a processor; and a memory having code embedded therein for programming the processor to control the apparatus to perform an image processing method that comprises; determining one or more regions of interest in said main image and said one or more further images; analyzing said one or more regions of interest; and determining to initiate a further action based on said analyzing of at least one region of interest, including applying a model to said at least one region of interest; analyzing one or more parameters of said model for said at least one region of interest to provide an indication that a characteristic of said at least one region of interest has at least a threshold value; segmenting from said main image or said one or more further images, or both, said at least one region of interest; comparing said at least one region of interest with at least one stored profile region also having at least said threshold value of said characteristic; and initiating said further action based on said analyzing of said at least one region of interest and on said comparing. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. One or more non-transitory, processor-readable media having code embedded therein for programming a processor to control an image acquisition and processing apparatus to perform an image acquisition and processing method that comprises:
-
determining one or more regions of interest in a main image and one or more further images approximately of a same scene within a time period including said acquiring of said main image; analyzing said one or more regions of interest; and determining to initiate a further action based on said analyzing of at least one region of interest, including applying a model to said at least one region of interest; analyzing one or more parameters of said model for said at least one region of interest to provide an indication that a characteristic of said at least one region of interest has at least a threshold value; segmenting from said main image or said one or more further images, or both, said at least one region of interest; comparing said at least one region of interest with at least one stored profile region also having at least said threshold value of said characteristic; and initiating said further action based on said analyzing of said at least one region of interest and on said comparing. - View Dependent Claims (16, 17, 18, 19, 20, 21)
