Abstract: A dynamic image processor for temporally analyzing the motion of each individual object contained in a dynamic image includes a rigid motion velocity vector extract unit for providing velocity vector data for rigid motion of the individual object; and a soft deformable motion velocity vector extract unit for providing velocity vector data for soft deformable motion after subtracting the rigid motion components. To plot the dynamic image, there are arranged a rigid motion velocity vector plot unit employing velocity vector data for the rigid motion of the individual object; and a soft deformable motion velocity vector plot unit employing velocity vector data for the soft deformable motion after subtracting the rigid motion components.

Abstract: A system for correctly detecting an edge of an image in which a first set of edges are corrected by a second set of edges which are detected as errors between an original image and a reproduced image obtained using the first set of edges. The edges may be in luminance components or lamellar chrominance components of a color image. A third set of edges obtained by applying a smaller threshold to the original image may be used to refine the second set of edges.

Abstract: A scalar data processing method and apparatus for compressing scalar data defined on a two-dimensional surface and for reconstructing the two-dimensional scalar data based on the compressed data. Edge lines of the scalar data are detected, a domain is obtained on a horizontal line intersecting with the edge lines and between the edge lines, and a function is determined as an approximation of a Laplacian of the two-dimensional scalar data at each point in the cut domain. The two-dimensional scalar data is compressed by replacing the two-dimensional scalar data at every point with scalar data at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the function determined above. The two-dimensional scalar data by interpolating the two-dimensional scalar data based on the scalar data is reconstructed at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the above function.

Abstract: A color picture image processing system for effecting hue processing and hue modification based on a derivation of chrominance components. A contour line determination unit determines a contour line in response to picture information and possibly sketch drawing information. A contour line chrominance providing unit determines a plurality of main points on the contour line and determines a chrominance main point vectors for the main points to provide chrominance contour vectors. The system includes a window unit for holding a new window setting resulting from processing a modification, a contour line modification unit for supplying instructions for modification of the contour line determined by the contour line determination unit and a contour line inner range chrominance processing unit for providing chrominance inner range vectors inside a range defined by the contour line.

Abstract: A color picture image processing system with edge detection for separating a color picture image into pixel data, transmitting vector signals constituting chrominance components of the pixel data in a corresponding relationship with a transmission of scalar signals corresponding to luminance components of the pixel data, and reproducing the color picture image from the transmitted vector signals and scalar signals.
