Title: Method for determining symmetric line of radiation image
Inventor: DEWAELE PIET
IPC: A61B6/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To generate an image having an axis of symmetry directed to a scheduled direction by calculating a point of symmetry as to each column (row) of the radiation image and connecting calculated points of symmetry to each other. SOLUTION: For each pixel at a certain position in a certain column, pixels in an aimed area or direct exposure area are excluded to find the maximum range of successive sums and the sum of symmetry differences around the center of assumed symmetry. Then reliability combined with the most symmetrical point of the column is found from a chain of a normalized symmetry measure and a combined reliability measure. Then linear minimum square adaptation to a data set and the combined measurement error is calculated from the chain of symmetry centers as to all columns and combined reliability measures so as to find the horizontal symmetry line of a position of an inspected body and a symmetry index corresponding to the horizontal symmetry line is calculated to obtain a perpendicular symmetry line and a combined symmetry index.

Title: Block encoder and decoder
Inventor: SHIGESATO TATSURO
IPC: H04N19/91
Filed: 1989-08-04
Abstract: PURPOSE:To minimize the deterioration in picture quality resulting from unable transmission of the last data by lending sequentially low frequency components important for visual sense at first so as to make the data rate constant. CONSTITUTION:An inputted sample is subject to block processing into small blocks for the unit of executing DCT(discrete cosine transformation) at a small block forming processing means 1 at first end rearranged orthogonal components are quantized by a quantization means 5. A quantized value obtained by the quantization means 5 is subject to variable length coding by a variable length coding means 6 and rearranged in the unit of a large block by a transmission means 7 and a lower frequency component is sent sequentially. When the data quantity after coding is too large and all code words cannot be sent, code words for higher frequencies whose transmission order is later cannot be sent, but since distortion of high frequency components is not eminent in general in a visual sense in comparison with the distortion of lower frequency components, the deterioration in the picture quality is minimized.
