TL;DR: An intra-operative medical image viewing system can allow a surgeon to maintain a viewing perspective on the patient while calling up visual images on-the-fly as mentioned in this paper, where a display is worn by the surgeon or positioned between the surgeon and her patient during surgery.
Abstract: An intra-operative medical image viewing system can allow a surgeon to maintain a viewing perspective on the patient while calling-up visual images on-the-fly. A digital image source has at least one image file representative of an anatomical or pathological feature of a patient. A display is worn by the surgeon or positioned between the surgeon and her patient during surgery. The display is selectively transparent, and exhibits to the surgeon an image derived from the image file. An image control unit retrieves the image file from the image source and controls the display so that at least a portion of the image depiction can be exhibited and modified at will by the surgeon. A plurality of peripheral devices are each configured to receive an image control input from the surgeon and, in response, generate an image control signal. Each peripheral accepts a different user-interface modality.

TL;DR: In this paper, the authors proposed a real-time method to convert an image from a first image format to a second image format in real time by buffering a stream of image data with a plurality of frame buffers in a controlled timing sequence.
Abstract: The invention provides a device which converts an image from a first image format to a second image format in real time. A stream of image data in the first image format is processed by a horizontal filter to convert a horizontal resolution of the image to the horizontal resolution of the second image format. After such processing, the horizontal filtered data is buffered by a plurality of frame buffers in a controlled timing sequence to convert a frame rate of the image to the frame rate of the second image format. After such processing, the buffered data is processed by a vertical filter to convert a vertical resolution of the image to the vertical resolution of the second image format.

TL;DR: In this article, an account number record is encoded onto a presentation instrument, and compared with the scanned visible account number, which is then compared with a scan of the account number with a reader.
Abstract: Systems and methods for producing a presentation instrument involve receiving an image file having an account number stamp, and producing the image file onto a piece of stock material, such that a visible account number corresponding to the account number stamp is created on the stock material. The visible account number is scanned with a reader. An account number record is encoded onto a presentation instrument, and compared with the scanned visible account number.

TL;DR: A new near-lossless image compression algorithm based on the Bayer format image suitable for hardware design that can provide low average compression rate with high image quality for endoscopic images and supports real-time compressing.
Abstract: In order to decrease the communication bandwidth and save the transmitting power in the wireless endoscopy capsule, this paper presents a new near-lossless image compression algorithm based on the Bayer format image suitable for hardware design. This algorithm can provide low average compression rate (2.12 bits/pixel) with high image quality (larger than 53.11 dB) for endoscopic images. Especially, it has low complexity hardware overhead (only two line buffers) and supports real-time compressing. In addition, the algorithm can provide lossless compression for the region of interest (ROI) and high-quality compression for other regions. The ROI can be selected arbitrarily by varying ROI parameters. In addition, the VLSI architecture of this compression algorithm is also given out. Its hardware design has been implemented in 0.18 µm CMOS process.

TL;DR: An automated system and method for storing document data in a Web based document management system is described in this article, which includes specifying a first identifier, scanning a document to produce an image file and resizing the image file to produce a resized image.
Abstract: An automated system and method for storing document data in a Web based document management system is provided. The method includes specifying a first identifier, scanning a document to produce an image file and resizing the image file to produce a resized image. The resized image has a width that is less than or equal to a maximum width at which a display unit can display the resized image entirely without resizing the resized image further or at which a printer can print the resized image entirely without further resizing the resized image. The method also includes extracting text data from the image file or the resized image file to produce a text file, uploading the text file and image file to a server, indexing the text file and image file in the server, and making the text file and image file accessible via the Internet by a web browser. Scanning, resizing, extracting, uploading, indexing and making are performed automatically substantially without manual interference between scanning, resizing, extracting, uploading, indexing and making.
