A method for reconstructing image information divided by a tree structure from a bitstream, includes: decoding the bitstream to reconstruct additional information, the additional information including first information on a minimum block size and second information on a difference between the minimum block size and a maximum block size, wherein the difference between the minimum block size and the maximum block size is a value of a log scale; reconstructing a partition flag indicating whether or not each node, starting from a node of an uppermost layer of the tree structure, is divided into nodes of a lower layer, the node of the uppermost layer identified based on the first and second information; and reconstructing image information of a block corresponding to a node which is not further divided.

A ground plane detection system including an imaging device operable to generate at least two images of a scene and an image processing assembly operable to receive the at least two images of the scene and to generate a model of each image and to perform homography computations through use of corresponding features in the models of each image.

A method and system for image processing is disclosed. An image processing system disposed on a data processing system generates a first thumbnail corresponding to an original image in response to an image display request. The image processing system decodes a first thumbnail in order to display the first thumbnail. The image processing displays the decoded first thumbnail on the data processing system. Region information corresponding to the first thumbnail is generated in the operation of decoding the first thumbnail. The region information indicates locations of a plurality of regions forming the original image.

A method for encoding a series of symbols using several models of the arithmetic or range coder type and including steps where each model is associated with a belonging criterion, the series is run through in order to determine, for each symbol, the encoding model to which each symbol belongs, according to the criteria; then a probability of occurrence of each symbol in the corresponding model is determined; then the series is run through by encoding each symbol successively; and a file is formed from the code thus obtained.

A detected quadrilateral area is displayed and no group of candidate lines is displayed in a normal state. While a user is selecting a side that the user desires to change, a group of candidate lines corresponding to the selected side is displayed. Then, whether to replace a position of the selected side with a position of a candidate line is determined based on a movement destination position of the selected side.

A method is described to greatly improve the efficiency of and reduce the complexity of image compression when using single-sensor color imagers for video acquisition. The method in addition allows for this new image compression type to be compatible with existing video processing tools, improving the workflow for film and television production.

Means which enables image conversion in which a plurality of conversion results can be output without once saving all of video-image data, which has been input from image-pickup means, in a storage medium is provided. A single line memory having a plurality of lines is used while switching the role thereof for a reading use by a video-image converting means and a use for inputting image data from the image-pickup means. The image converting means obtains an input image, which is in the line memory, and carries out conversion of the input image based on a conversion specifying means interpreted by an instruction decoder.

Technologies are generally described for detection and tracking of item features. In some examples, features of an object may be initially found through detection of one or more edges and one or more corners of the object from a first perspective. In addition, determination may be made whether the detected edges and corners of the object are also detectable from one or more other perspectives. In response to an affirmative determination, the detected edges and of the object may be marked as features to be tracked, for example, in subsequent frames of a camera feed. The perspectives may correspond to distributed locations in a substantially umbrella-shaped formation centered over the object. In other examples, lighting conditions of an environment where the object is being tracked may be programmatically controlled.

A terminal device includes an acquisition unit that acquires image information of a read-out original, a display unit that displays the image information acquired by the acquisition unit, a detection unit that detects pitch information by performing frequency analysis of the image information displayed by the display unit, and a control unit that controls the image information so as to be enlarged or reduced in accordance with a size of the original and controls to display the pitch information so as to be superimposed on the image information which is enlarged or reduced.

Method and apparatus for the digital encoding of a first raw file, the method includes: a first step of capturing the raw file, the raw file being an audio and/or image and/or video file; a second step of encoding the captured raw file into a second file, in a proprietary format (P); then, a third step for re-encoding the second file into a third file in a compatible format (C).
