Abstract: An image-processing device includes: a gradient data generation unit which sequentially targets pixels, and on the basis of a luminance value, generates gradient data in which each pixel is represented using a first label of a value indicating a direction toward a pixel having a higher luminance value or a second label of a value indicating that the luminance value of the pixel is higher than all pixels located around the pixel; a plurality of region label generation units which set each pixel represented by the second label as a peak pixel, divide regions into regions including pixels belonging to the same peak pixel on the basis of peak coordinates indicating the positions of peak pixels, and generate region label data; and a peak pixel distribution unit which distributes each peak pixel to each of the region label generation units such that loads of computations are approximately equalized.

Abstract: A method and apparatus for detecting defects on tyres in a tyre production process. The method includes: receiving a reference image of a surface portion of a reference tyre substantially defects-free; providing a sample tyre to be analysed; illuminating a surface portion of the sample tyre with a raking light source; acquiring a sample image of the illuminated surface portion of the sample tyre; extracting the edges from the reference image and from the sample image and respectively generating an edge reference image and an edge sample image; carrying out a dilation of the edges of the edge reference image and generating therefrom a dilated edge reference image; comparing the edge sample image with respect to the dilated edge reference image and generating an edge image of possible defects; and identifying the edges in the edge image of possible defects.

Abstract: A manufacturing method of single crystal is provided with a melting process for dissolving raw material in a crucible and a pulling-up process of a single crystal from a melt by the Czochralski method. The pulling-up process includes detecting an edge line of a fusion ring, determining an approximated curve of the edge line by approximating the edge line of the fusion ring by an even function, eliminating constituent pixels of the fusion ring from the image of the fusion ring as noise, the constituent pixels being positioned on the side of the melt relative to the approximated curve and the constituent pixels of the fusion ring and a deviation between the constituent pixels and the approximated curve being a predetermined number of pixels, and calculating the center position of the single crystal from the edge line of the fusion ring from which the noise has been eliminated.

Abstract: A method for facilitating removal of specular reflection noise from light data can include illuminating, using an illumination unit, a target with a light source. The illumination unit is configured to project light with a spatial light pattern onto the target. The method can also include acquiring, with a sensor unit, light data that is reflected from the target. The light data may comprise a directly reflected spatial light pattern and a specular reflected spatial light pattern. The directly reflected spatial light pattern and the specular reflected spatial light pattern comprise at least one spatial distinction that distinguishes the directly reflected spatial light pattern from the specular reflected spatial light pattern. The method can further comprise processing the light data to distinguish the directly reflected spatial light pattern from the specular reflected spatial light pattern based upon the at least one spatial distinction.

Abstract: Each projection apparatus in a multi-projection system has a liquid crystal panel, a driving circuit configured to perform PWM control of the liquid crystal panel, and a projection image processing unit configured to perform edge blending processing to perform compositing display by each projection apparatus and processing to change gain properties of the edge blending processing by each projection apparatus. Synchronization of each projection apparatus is maintained by a synchronization circuit. Therefore, a sum of image gain in a region of image compositing by each projection apparatus is 1, and the position and image gain properties of the compositing region are changed for each frame, so the position of image deterioration changes for each frame.

Abstract: An image processing method separates an input image into a skeleton component, and residual component. In the method a local variation amount, which is a variation amount between a target pixel and a pixel adjacent to the target pixel, is calculated; a skeleton component extraction filter weight is calculated based on the local variation amount; an image feature amount of a gradient direction of a pixel value around the target pixel, and an image feature amount of a gradient strength of the pixel value around the target pixel, are calculated; the skeleton component extraction filter weight is corrected based on these image feature amount; a skeleton component extraction filter coefficient is calculated based on the corrected skeleton component extraction filter weight; and the skeleton component is extracted by applying skeleton component extraction filtering to the target pixel using the calculated skeleton component extraction filter coefficient.

Abstract: An image processing apparatus and method thereof are provided. The image processing apparatus includes a false contour detection circuit and a false contour reduction circuit. The false contour detection circuit includes detection modules and a determination module. The detection modules respectively detect different features of the same image input signal and correspondingly output feature coefficients. The determination module is coupled to the detection modules and determines a false contour coefficient according to the feature coefficients. The false contour reduction circuit is coupled to the determination module of the false contour detection circuit to receive the false contour coefficient and perform false contour reduction on the image input signal according to the false contour coefficient, so as to output a corresponding image output signal.

Abstract: A computer-implemented depth estimation method based on non-parametric Census transform with adaptive window patterns and semi-global optimization. A modified cross-based cost aggregation technique adaptively creates the shape of the cross for each pixel distinctly. In addition, a depth refinement algorithm fills holes within the estimated depth map using the surrounding background depth pixels and sharpens the object boundaries by exerting a trilateral filter to the generated depth map. The trilateral filter uses the curvature of pixels as well as texture and depth information to sharpen the edges.

Abstract: The present principles relate to a method and a device for reducing noise in a component of a picture. The method includes obtaining a low-pass filtered component by low-pass filtering the component of the picture, for a current pixel in the component of the picture. For at least one current neighboring pixel of the current pixel, computing a distance, relative to the current neighboring pixel, between the value of the current pixel in the low-pass filtered component and the value of the current neighboring pixel in the low-pass filtered component. When the distances relative to the at least one neighboring pixels of the current pixel are lower than a first threshold, modifying the value of the current pixel in said component of the picture according to a linear combination of the value of the current pixel in the component of the picture and the value of the current pixel in the low-pass filtered component. Otherwise the value of the current pixel in the at least one component of the picture remains unchanged.
