摘要： The subject application is directed to a system and method for image enhancement. Image data is received that contains a rectangular array of pixels encoded in a multidimensional color space. The image data is scaled to a scaled rectangular array having a smaller number of pixels such that both a selected rectangular dimension and a complimentary dimension are scaled to preselected dimension values. Region-of-interest data is received for an isolated region in the image data. A mask matrix, having a rectangular array of elements corresponding to pixels of the scaled rectangular array, is stored. The mask matrix, populated using region-of-interest data, has first and second values associated with each entry, with the first value, but not the second value, corresponding to a region of interest in the scaled rectangular array. Received image data is adjusted according to image data values based on pixel values associated with first value elements.

摘要： A method for determining an indication of how well-focused an image is. An image is divided into a plurality of blocks. At least one local measure is determined for at least one block of the plurality of blocks. At least one global figure-of-merit is determined for the image based on the local measure. An indication of focus is determined based on the global figure-of-merit.

摘要： The subject application is directed to a system and method for facial tone indexing. Image data comprised of a plurality of pixels encoded in at least a three dimensional component space is received and at least one candidate facial region is isolated in the received image data. The received image data is translated into a Lightness, Chroma, and Hue color space. Histogram data corresponding to the Hue of pixels is calculated in the at least one candidate facial region by discarding the low-chroma pixels first. The Hue index on which the Hue histogram peaks is identified as the Facial Tone Index. The Facial Tone Index indicates where the Hue concentration is and therefore is a single number representing the flesh tone of a face.

摘要： In one aspect, a metadata-based classification result is obtained based on metadata associated with an image. A histogram-based classification result is determined based on a histogram of intensity values derived from the image. The image is classified into a scene type class based on the metadata-based classification result and the histogram-based classification result. In another aspect, a first condition is applied on a first one of metadata associated with an image corresponding to a measure of amount of light received in capturing the image to obtain a first metadata-based classification result. A second condition is applied on a second one of the metadata corresponding to a measure of brightness of the image to obtain a second metadata-based classification result. The image is classified into a scene type class based on the first and second metadata-based classification results.

摘要： The subject application is directed to a system and method for isolating near achromatic pixels of a digital image. First, image data encoded as a plurality of pixels is received, with each pixel having component values in a multi-dimensional color space. From the received image data, chroma data is extracted. Histogram data is then calculated from the extracted chroma data. An adapted threshold value is then determined based upon the calculated histogram data. Component values of the plurality of pixels are then compared to the determined adapted threshold value. Isolation of pixels as near achromatic then occurs in accordance with the output of the comparison of the adapted threshold value to the component values.

摘要： Systems and methods of detecting and correcting redeye in an image are described. In one aspect, the input image is sub-sampled to generate a thumbnail image, redeye pixel areas are detected in the thumbnail image. In another aspect, an input image having lines of pixels with original color values is processed. One or more redeye pixel areas corresponding to respective areas in the input image are detected. Each pixel in the input image corresponding to the detected redeye pixel areas is classified as a redeye pixel or a non-redeye pixel on a line-by-line basis without reference to pixels in adjacent lines. The original color values of pixels in the input image classified as redeye pixels are corrected.

摘要： Systems and methods for extracting a graphical bar code (i.e., an image that contains inconspicuous graphical modulations that encode embedded information) from an input image are described. In one aspect, estimates of position coordinates for a detected graphical bar code candidate are computed. An objective function is optimized based on the computed position coordinates to obtain final position coordinate estimates for the graphical bar code candidate. Non-graphical bar code regions are trimmed from the input image based on the final position coordinates for the graphical bar code candidate to produce a trimmed graphical bar code candidate for decoding.

摘要： Peteye is the appearance of an unnatural coloration (not necessarily red) of the pupils in an animal appearing in an image captured by a camera with flash illumination. Systems and methods of detecting and correcting peteye are described. In one aspect a classification map segmenting pixels in the input image into peteye pixels and non-peteye pixels is generated based on a respective segmentation condition on values of the pixels. Candidate peteye pixel areas are identified in the classification map. The generating and the identifying processes are repeated with the respective condition replaced by a different respective segmentation condition on the pixel values.
