摘要： Important information about an object is detected using less arithmetic processing. An object detection unit generates an edge image from a color image. The object detection unit evaluates symmetry of an image included in the edge image. The object detection unit identifies a symmetry center pixel forming an object having symmetry. The object detection detects an object width for each symmetry center pixel. The object detection unit identifies the width of the object in the vertical direction based on the width of the symmetry center pixels in the vertical direction, and identifies the width of the object in the horizontal direction based on the object width identified for each symmetry center pixel.

摘要： A pixel interpolation apparatus, an imaging apparatus, a program, and an integrated circuit allow appropriate pixel interpolation processing on an image signal obtained by a single-chip image sensor having a WRGB color filter array. An imaging apparatus includes an imaging unit, a signal processing unit, and a pixel interpolation processing unit. The apparatus calculates a degree of correlation for pairs in two orthogonal directions for an image signal (Raw image) obtained by the imaging unit including a single-chip image sensor having a WRGB color filter array using pixel data in an area around a target pixel, using the correlation degree as a determination criterion in the interpolation processing. The imaging apparatus selectively uses a luminance signal generated from R, G, and B-component signals or a luminance signal generated from a W-component signal to perform pixel interpolation processing with higher accuracy and obtain a YCbCr signal with higher accuracy.

摘要： Provided is a state determination apparatus that appropriately performs pattern classification processing and/or pattern determination processing even when a map generated by the SOM technique includes discontinuous image regions. In the state determination apparatus, the matching processing unit obtains adaptability data indicating a correlation degree between template data indicating a state and the SOM output data. The state determination unit obtains a state evaluation value based on an activity value obtained by the activity value obtaining unit and the adaptability value. The time series estimation unit determines a state of an input data based on the state evaluation value and state transition probability between states. This allows for appropriately performing pattern classification processing and/or pattern determination processing even when a map generated by the SOM technique includes discontinuous image regions.

摘要： A moving object controller efficiently generates an environmental map and performs highly accurate state estimation in a short time to appropriately control a moving object. An observation obtaining unit obtains observation data from an observable event. A landmark prediction unit generates a landmark prediction signal including predictive information about a landmark at a current time. A landmark detection unit detects information about the landmark at the current time, and generates a landmark detection signal indicating the detection result. A state estimation unit estimates an internal state of the moving object to obtain data indicating an estimated internal state of the moving object at the current time, and estimates the environmental map based on the landmark detection signal to obtain data indicating an estimated environmental map at the current time.

摘要： A state estimation apparatus appropriately estimates the internal state of an observation target by calculating a likelihood from observation data, and tracks, for example, multiple objects in a moving image and detects a new object and adds the object as a tracking target in an appropriate manner. A labeling unit detects a closed area from an observation image, and adds a label number to the closed area to generate a label image. A likelihood obtaining unit generates an object-erased image for new object detection by erasing image areas corresponding to all the currently-tracked objects. The apparatus performs the process for detecting a new object using the object-erased image for new object detection based on label numbers. The apparatus is appropriately prevented from erroneously determining that an area of the object-erased image for new object detection corresponding to the currently-tracked object and remaining after the erasure corresponds to a new object.

摘要： Provided are a pixel interpolation apparatus, imaging apparatus, program, and integrated circuit that appropriately perform pixel interpolation on an image signal obtained by a single-chip image sensor with a four-color array filter whatever array pattern the four-color array filter has. An imaging apparatus includes an imaging circuitry, a signal processing circuitry, and a pixel interpolation processing circuitry. The apparatus calculates a degree of correlation for pairs in two orthogonal directions for an image signal obtained by the imaging circuitry including a single-chip image sensor having a four-color array filter using pixel data in an area around a target pixel, and performs pixel interpolation using the correlation degree as a determination criterion. When a color component pixel with a color identical to a color of a color component pixel subjected to pixel interpolation is not located in the direction having the high correlation, the pixel interpolation apparatus obtains a change ratio in a direction orthogonal to the direction having the high correlation by using a pixel value resulting from color space conversion in the direction orthogonal to the direction having the high correlation, and performs pixel interpolation processing based on the change ratio.

摘要： It is an object of the present invention to provide an image coding technique for suppressing degradation in image quality, in which the time and space where intra macroblocks appear are dispersed. A block count determination part determines the number of intra macroblocks to be allocated in each frame. A position determination part arranges the intra macroblocks at random positions in each frame. A coding part performs coding on the basis of the number of intra macroblocks to be allocated in a time direction, which is determined by the block count determination part, and the arrangement of the intra macroblocks in a spatial direction, which is determined by the position determination part, to thereby output compressed image data.

摘要： In an object detection apparatus 1, a window definer 11 defines a window relative to the location of a pixel in an input image 20. A classification value calculator 13 calculates a classification value indicative of the likelihood that a detection target is present in the window image contained in the window based on the feature data of the detection target. A classification image generator 14 arranges the classification value calculated from the window image according to the pixel location to generate a classification image. An integrator 15 integrates the classification image and a past classification image 42 generated from a past input image input prior to the input image 20 to generate an integrated image 45. A determiner 16 determines whether the detection target is present in the input image 20 based on the integrated image 45.
