Systems and methods of face and skin sensitive image enhancement are disclosed. In one aspect, a face map that includes for each pixel of an input image a respective face probability value indicating a degree to which the pixel corresponds to a human face is calculated. A skin map that includes for each pixel of the input image a respective skin probability value indicating a degree to which the pixel corresponds to human skin is ascertained. The input image is enhanced with an enhancement level that varies pixel-by-pixel in accordance with the respective face probability values and the respective skin probability values. In another aspect, a facial content measurement value indicating a degree to which an input image contains human face content is ascertained. A tone-correction process is tuned in accordance with the facial content measurement value. The input image is enhanced in accordance with the tuned tone-correction process.

Image forming devices, hard imaging methods, and methods of determining a transfer function are described. According to one embodiment, an image forming device includes an image engine configured to provide a marking agent upon media, processing circuitry configured to control the image engine to form a test image upon the media having a specified coverage of the marking agent and to access measurement data indicative of a measured coverage of the marking agent of the test image, storage circuitry configured to store data comprising associations of a plurality of specified coverage values of the marking agent and a plurality of resultant coverage amounts of the marking agent formed upon the media by the image engine corresponding to respective ones of the specified coverage values, and wherein the processing circuitry is further configured to access image data of an image to be formed to identify one of the specified coverage values of the marking agent to be formed upon the media to form the image, to modify the one specified coverage value using the stored data and the measurement data to provide an imaging coverage value, and to control the image engine using the imaging coverage value to form the hard image.

摘要:
Modification of a digital image includes determining a likelihood of a pixel belonging to a memory color region (110). The memory color region has a preferred color. The modification further includes shifting original color of the pixel toward the preferred color (120). The original color is shifted by an amount that is a function of the likelihood and that is generally less than the difference between the original and preferred colors.
摘要:
Event analysis methods and apparatus in which sequences (44, 46) of one or more events are identified based on event records (20) describing the events. Respective distance values (28) representing distances between ones of the sequences (44, 46) are determined. A configuration of points in a target metric space is constructed based on the distance values (28), where each of the points represents a respective one of the sequences (44, 46). A visual representation (38) of the configuration is presented on a display (34).
