Apparatus and methods for detecting salient features. In one implementation, an image processing apparatus utilizes latency coding and a spiking neuron network to encode image brightness into spike latency. The spike latency is compared to a saliency window in order to detect early responding neurons. Salient features of the image are associated with the early responding neurons. A dedicated inhibitory neuron receives salient feature indication and provides inhibitory signal to the remaining neurons within the network. The inhibition signal reduces probability of responses by the remaining neurons thereby facilitating salient feature detection within the image by the network. Salient feature detection can be used for example for image compression, background removal and content distribution.

Some embodiments provide a method and system for efficiently transferring medical images. Some embodiments receive a medical image in a first platform dependent format of a Picture Archiving and Communication System (PACS). The first platform dependent format is one that is accessible by a first format compliant device that includes a library that specifies how to decode the first format. Some embodiments transform the medical image from the first format to a second format. The second format includes decoded content of the first format that is viewable on a first format non-compliant device. The transformed image is then passed to the device for viewing. Additionally, some embodiments efficiently transfer medical images by identifying image settings for one or more devices and by passing requested images that are optimized by resizing the images according to the image settings of the requesting device.

When a subject is imaged for the purpose of deciding the angle of view, the full image that is capable of being sensed by a CCD is displayed on an LCD. The user designates the position of a cropping area in the image being displayed. Only image data representing the image within the border of the designated area is recorded on a memory card. Since the amount of image data to be recorded on the memory card is thus reduced, image data representing images of a greater number of frames can be recorded on the memory card.

A light-source drive control unit divides each pixel of the image data into a plurality of subpixels, deletes certain subpixels from the image data in accordance with predetermined correction data, shifts remaining subpixels in the sub-scanning direction thereby obtaining reduced image data, and controls a plurality of light sources based on the reduced image data in such a manner that one line of the subpixels is formed with a light beam emitted from a corresponding one of the light sources.

The invention discloses a moving object extraction method based on superpixel division and an optical flow method, and mainly solves the problems of more noises, high-frequency information loss, inaccurate boundary and the like of the existing moving object extraction method. The implementation steps of the method are as follows: (1), inputting an image, and pre-dividing the image into a superpixel set S to obtain a mark sheet I 2; (2), taking images of two adjacent frames in a video sequence and determining a rough position of a moving object by a Horn-Schunck optical flow method; (3), using the optical flow method to obtain the speed u in the horizontal direction and the speed v in the vertical direction, wherein V is speed amplitude of the optical flow method; (4) performing median filtering, Gauss filtering, binarization operation and morphology opening and closing operation on the optical flow result V to obtain V4; (5) using a superpixel division result to further correct the optical flow result, and extracting to obtain the accurate moving object. Superpixels belonging to a moving area are extracted accurately. Simulation experiments show that compared with the prior art, the moving object extraction method has the advantages of simple operation, small noise, clear boundary and the like, and can be used for extracting the moving object in the video sequence.

A codec device is disposed in a display control device for instantly supplying decompressed image data to manipulating devices in the display control chip. Reference images are stored in compressed format after instantly compressed by the codec device. In addition, MSB portions and LSB portions are separately compressed for gaining higher compression ratio. Predication of the pixel value is also modified in variable length coding. On-chip line buffer is also applied with the instant compression mechanism. Fixed compression ratio is predetermined to actually downsize the chip design for the worst case.

The present invention relates to systems and methods for compiling communication material across a range of formats. A first aspect of the present invention relates to a method of editing an image for printing. The image data for a high resolution image is stored and the image is displayed at a lower resolution. The user can then edit the displayed image and image modifier data is generated based on the editing performed by the user. The image modifier data is subsequently applied to the stored high resolution image data and a modified version of the image is output based on said modified high resolution image data. The present invention also relates to a system and method for monitoring an electronic file. Furthermore, the present invention relates to a system and method of sharing data across a range of different templates for online and print material. The invention also relates to a system and method of generating online and print material in a common file format.

A portable terminal apparatus confirms whether it conforms to an image data sending and receiving method to which an image forming apparatus for printing image data can be adapted, and receives data of the printable image format from the image forming apparatus. The portable terminal apparatus displays image identification data for identifying each piece of stored image data, and determines whether each piece of the image data is printable, based on at least one of a result of the confirmation with respect to the sending and receiving method, the image format information, and the image data. Based on a result of the determination, the display is controlled so that the user can distinguish whether each piece of the image data is printable. Among image data selected by the user, printable image data due to the determination is sent to the image forming device.

A defect inspection apparatus is provided which allows a technology for inspecting a pattern on a wafer by using an electron beam to implement a high-resolution and higher-speed inspection. A semiconductor wafer is irradiated with an electron beam and electrons reflected in the vicinity of the wafer are detected. The presence or absence of a defect and the location thereof are measured by forming an image from only a component which changes with a periodicity larger than a size of a circuit pattern or the repetition periodicity thereof by using lenses and comparing an image signal with a preset value. Since only the component which changes with a periodicity larger than the size of the circuit pattern with a surface potential distortion and the repetition periodicity thereof is observed with a resolution lower than required to observe the pattern itself instead of detecting a defect through a comparison between extremely small pattern images, an inspection throughput can be increased exponentially compared with that of a conventional SEM inspection.
