Abstract: A facility inspection system prevents a normal part from being detected as an abnormal part caused by a deviation in an alignment due to a presence/absence of a moving object in detecting the abnormal part in a surrounding environment of a vehicle moving on a track. The system includes a photographing device, storage device, separation unit, an alignment unit, and a extraction unit. The photographing device photographs the surrounding environment of the moving vehicle. The storage device stores a reference alignment point cloud and a reference difference-extraction point cloud for each position on the track. The separation unit separates the alignment point cloud from a three-dimensional point cloud. The alignment unit aligns the reference alignment point cloud and the alignment point cloud and outputs alignment information. The extraction unit extracts a difference between the three-dimensional point cloud deformed based on the alignment information and the reference difference-extraction point cloud.

Abstract: Provided is an image processing apparatus that can reduce degradation in image quality due to heat haze and the like. An input image memory 110 stores an input image group 200 and an input image 210. A time-series smoothed image memory 112 stores a time-series smoothed image 220 obtained by time series smoothing. A moving body removed image memory 113 stores a moving body removed image 230 that is a background image. A histogram analyzing unit 130 computes a differential of histograms of partial images for the input image 210 and the time-series smoothed image 220 or the moving body removed image 230, and calculates similarity information between the images. On the basis of the similarity information, a region dividing unit 140 divides the input image 210 into a moving body region, and a region other than the moving body region. An image correcting unit 150 performs image synthesis of the input image 210 or the time series-smoothed image 220, for each of the regions.

Abstract: An image encoding device that appropriately estimates a prediction vector by avoiding an uncoded macro block (MB) is disclosed. The device determines a start point of searching a motion vector for an encoding target region, from the prediction vector for the target region which is determined with motion vectors for surrounding blocks around the target region and in accordance with a predetermined rule, and starts searching for the motion vector from the search start point. If the size of the encoding target region cannot be acquired during calculation of the prediction vector, the device determines the size of the encoding target region, from the size of an encoded region other than the target region. If at least one of the motion vectors for the surrounding blocks cannot be acquired, the device calculates the prediction vector using alternatively a motion vector of an encoded block outside of the target region.

Abstract: Suppression of prediction error accumulating in an intra prediction is described. A motion picture encoding apparatus that performs encoding processing for each pixel block using a motion picture encoding method includes intra prediction processing for generating a prediction image using correlation of pixels therearound, and in the intra prediction processing, the motion picture encoding apparatus has processing for generating a quasi-prediction image from an input image, wherein when a prediction mode is determined, a weight is given to a pixel serving as a reference pixel in the intra prediction processing, and thus, the prediction mode is determined. When the weight is set at one or more, an error of a pixel serving as a reference pixel in a subsequent block is emphasized, and therefore, a prediction mode that is likely to propagate the error to the subsequent block is less likely to be selected.
