    摘要： Dominant color names may be extracted from an image by analyzing spatial-context of pixels contained in the image. A dominant color region may be defined by taking a double-threshold approach that addresses ambiguous color regions and a degree of confidence that each pixel belongs in the dominant color region. Affiliation maps and binary maps may be used to generate the dominant color region. Images may be converted to a saliency map, from which a region of interest may be assigned a dominant color name. Image search results may be filtered by the dominant color name associated with the image.

    摘要： An exemplary file manipulation method determines whether the user manipulation on the file or file folder is a moving manipulation. The method then reads a directory structure of each drive from a storage unit when detecting that the user manipulation on the file or file folder is the moving manipulation, determines a maximum folder depth of the directory structure of the one or more drives, and further controls to display a user interface showing the directory structure with the maximum folder depth. Next, the method detects the user manipulation in the user interface, and determines a position where the icon is dragged to is a target position when detecting that the user manipulation is dragging the icon to the position in the ring portion of the sector. The method then moves the manipulated file or file folder to a target drive or file folder corresponding to the target position.

    摘要： A needle is enhanced in a medical diagnostic ultrasound image. The image intensities associated with a needle in an image are adaptively increased and/or enhanced by compounding from a plurality of ultrasound images. Filtering methods and probabilistic methods are used to locate possible needle locations. In one approach, possible needles are found in component frames that are acquired at the same time but at different beam orientations. The possible needles are associated with each other across the component frames and false detections are removed based on the associations. In one embodiment of needle detection in an ultrasound component frame, lines are found first. The lines are then searched to find possible needle segments. In another embodiment, data from different times may be used to find needle motion and differences from a reference, providing the features in additional to features from a single component frame for needle detection.
