Image processing method and apparatus

摘要

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 analyzed 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 analyzed 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.

主权项

1. An image processing method comprising:
using a processor-based image acquisition device to acquire a main image of a scene and two or more further images approximately of a same scene within a time period; wherein said time period begins proximately before said acquiring of said main image and ends proximately after said acquiring of said main image; using one or more computing devices to perform the steps of:
determining that a particular object in said main image has a defect;identifying two or more defect free objects, from the two or more further images, that correspond to the particular object;creating a corrective object that corresponds to the particular object by combining together said two or more defect free objects;performing a comparison between said particular object and said corrective object; anddetermining whether to initiate a further action based on said comparison.
