  • Patent number: 7711183
    Abstract: A method generates a composite image by painting unfilled regions between micro-objects with other micro-objects to create a multiple layer effect. Another method generates a composite image from as few as one micro-object by changing the average color and/or intensity of the micro-object to match that of an area on the source image. Yet another method quickly generates a preview image of a composite image by saving the micro-objects in multiple resolutions so that the micro-objects at the small resolution can be quickly scaled to build a preview image of the composite image.

  • Patent number: 7706590
    Abstract: A method of using laser scanning cytometry to provide a viewable image of a specimen includes impinging a beam of light from a light source on the specimen and positioning a detector such that the detector captures only a portion of an unimpinged beam from the light source, and the detector captures forward scattered light from the beam after the beam impinges the specimen. Forward scattered light from the beam is captured with the detector after the beam impinges the specimen to produce an image of the specimen, and the position of the detector is adjusted to control the contrast of the image.

  • Patent number: 7697785
    Abstract: In one embodiment, the present invention extracts video regions of interest from one or more videos and generates a highly condensed visual summary of the videos. The video regions of interest are extracted based on to energy, movement, face or other object detection methods, associated data or external input, or some other feature of the video. In another embodiment, the present invention extracts regions of interest from images and generates highly condensed visual summaries of the images. The highly condensed visual summary is generated by laying out germs on a canvas and then filling the spaces between the germs. The result is a visual summary that resembles a stained glass window having cells of varying shape. The germs may be laid out by temporal order, color histogram, similarity, according to a desired pattern, size, or some other manner.

  • Patent number: 7689054
    Abstract: A device is described in which a visual image can be enhanced to better recognize different objects that appear in a picture. Means are provided for an operator to manipulate a visual image by adjusting darkness levels within each primary color to embellish the recognition of distinct objects which may appear in the visual rendering. The device may be implemented as a ground-based system where the operator can adjust the algorithm to manipulate the darkness levels of a certain number, N, of pixels. A second implementation can be achieved in a helmet mounted display or glasses donned by an operator.

  • Patent number: 7684632
    Abstract: Methods, machines, systems and machine-readable instructions for processing an image are described. In one aspect, the image is divided into a population of image blocks. Frequency domain vectors are generated from respective ones of the image blocks. Each of the frequency domain vectors includes a respective set of values corresponding to a set of transform coefficients. Preliminary estimates of quantization parameter values are determined from frequency distributions of the transform coefficient values in a set of the frequency domain vectors corresponding to a variable sample of the population. The variable sample is determined at least in part by at least one threshold. Values of quantization parameters are estimated from the preliminary estimates.
