Pixel image enhancement system and method

A pixel image enhancement system which operates on color or monochrome source images to produce output cells the same size as the source pixels but not spatially coincident or one-to-one correspondent with them. By operating upon a set of input pixels surrounding each output cell with a set of logic operations implementing unique Boolean equations, the system generates "case numbers" characterizing inferred-edge pieces within each output cell. A rendering subsystem, responsive to the case numbers and source-pixel colors, then produces signals for driving an output device (printer or display) to display the output cells, including the inferred-edge pieces, to the best of the output device's ability and at its resolution.

At least one image of the environment is taken using either an image capturing device of the monitoring system. Based on the image of the environment, at least one background image is generated. The background image, which comprises a plurality of pixels, is divided into pixel blocks. In each pixel block, at least one data cluster is formed using at least one feature of the pixels in the pixel block. The data cluster formed in each pixel block is described as a data distribution having a mean value and a standard deviation from the mean value. After generating the background image, a subsequent image is taken by the monitoring system. Each pixel of the subsequent image is compared with the data cluster of the block of the background image correspond to the pixel, and a first discrepancy value is generated accordingly. The pixel of the subsequent image is further compared with the data distribution of at least another pixel block which is adjacent to the pixel block of the background image corresponding to the pixel, and a second discrepancy value is generated as a result of this comparison. Based on the first and second discrepancy value, the pixel of the subsequent image is determined to be either a background pixel or a foreground pixel. After all the pixels in the subsequent image have been determined as either a background or a foreground pixel, a binary map is generated. The connected foreground pixels in the binary map are marked to form a foreground object, which is the detected objected in the environment according to the invention.

Determining Material Stiffness Using Multiple Aperture Ultrasound

Changes in tissue stiffness have long been associated with disease. Systems and methods for determining the stiffness of tissues using ultrasonography may include a device for inducing a propagating shear wave in tissue and tracking the speed of propagation, which is directly related to tissue stiffness and density. The speed of a propagating shear wave may be detected by imaging a tissue at a high frame rate and detecting the propagating wave as a perturbance in successive image frames relative to a baseline image of the tissue in an undisturbed state. In some embodiments, sufficiently high frame rates may be achieved by using a ping-based ultrasound imaging technique in which unfocused omni-directional pings are transmitted (in an imaging plane or in a hemisphere) into a region of interest. Receiving echoes of the omnidirectional pings with multiple receive apertures allows for substantially improved lateral resolution.
