摘要： As provided herein, there are supplied teachings to systems and methods for resizing a halftone image using halftone tile parameters. One approach entails receiving into a digital imaging system, a digital halftone image and a desired resizing factor for the digital halftone image. Subsequently the system will define cells within the digital halftone image and determine from those cells, a number of halftone tile seams to suitable for manipulation. The orientation of these halftone tile seams is dictated by the received desired resizing factor. The energy of the number of halftone tile seams is determined according to an energy metric so as to provide indication of at least one low energy determined halftone tile seam. A resizing of the halftone image is then performing by manipulating at least one low energy halftone tile seam in the halftone image. The resized halftone image may then be printed on a printer.

摘要： In accordance with the present disclosure, there is provided a method for compensating tones on a compressed digital image data. The method comprises generating the compressed digital image from an input digital image data using a wavelet-based compression method; recovering a low resolution version of the input digital image data from the compressed digital image data by partially decompressing the compressed digital image; applying compensating tone reproduction curves (TRC) to the low resolution version of the input digital image data to generate a compensated low resolution image; re-compressing the image using the compensated low resolution image; and, subsequently decompressing all of the compensated pixel arrays to produce decompressed compensated image data.

摘要： In accordance with the present disclosure, there is provided a method for performing streak compensation on compressed digital image data. The method comprises generating the compressed digital image data using a compression method employing a discrete cosine transform (DCT) and recovering a zero frequency component (DC coefficient) of the discrete cosine transform (DCT) for each of a plurality of compressed unit blocks of image data wherein each unit block includes N pixel columns. The method further comprises applying spatially varying compensating tone reproduction curves (TRC) to the DC coefficients of each of the plurality of unit blocks on a block-column basis wherein each block-column receives compensation from a given TRC, re-compressing the compensated image data, and subsequently decompressing all of the compensated units to produce decompressed compensated image data.

摘要： A camera may be positioned to have a direct view of on-coming vehicle traffic from a first perspective. Additionally, a reflective surface, such as a mirror, may be positioned within the viewing area of the same camera to provide the camera with a reflected view of vehicle traffic from a second perspective. The images recorded by the camera may then be received by a computing device. The computing device may separate the images into a direct view region and a reflected view region. After separation, the regions may be analyzed independently and/or combined with other regions, and the analyzed data may be stored. The regions may be analyzed to determine various vehicle characteristics, including, but not limited to, vehicle speed, license plate identification, vehicle occupancy, vehicle count, and vehicle type.
