Title: Information imbedding method, system and recording medium thereof
Inventor: YODA AKIRA
IPC: H04N1/32
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To imbed supplementary information to image data by way of deep layer encryption. SOLUTION: A table-generating means 3 generates a table that indicates, to which color coordinate in a 2nd color space a color coordinate of a 1st color spaces is to be mapped, based on a quantization error in the case of converting image data S0 residing in the 1st color space to the 2nd color space which is a conversion destination. A coding means 2 encodes information H0 to be imbedded by referencing the table to obtain coded supplementary information H1. In converting the image data S0 by a color conversion means 1, the supplementary information H1 is imbedded in a quantization error, to obtain image data S1 to which the supplementary information H1 is imbedded.

Title: Method for correcting behavior of strip in rolling of strip and device therefor
Inventor: SUDDERTH STELLA M
IPC: B21B37/68
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To correct the traveling behavior of a strip extremely easily and accurately by measuring a measured value which shows tensile internal stress, calculating difference from the tensile internal stress by making the value into an actual value with a control circuit and, in the case the actual value is different from the reference value, adjusting the traveling of the strip at least by rolling force of the rolls of a roll stand. SOLUTION: A rolling line consists of two roll stands 1, 1' and has work rolls 2a, 2b, 2a', 2b'. By providing devices 4 for measuring the tensile internal stress of the strip between both the roll stands 1, 1' and measuring the measured values which show the tensile internal stress with the measuring devices 4 on the opposite side of the running-out strip 5, the difference from the tensile internal stress is calculated by making the values into the measured value in the control circuit. When the actual value is different from the reference value, by changing rolling force of the roll by making the gap between the rolls 2a, 2b of one roll stand 1 smaller, the behavior of the strip 5 is corrected. The value of the tensile internal stress is measured with a load cell.

Title: Image processor
Inventor: HIKOSAKA ARINORI
IPC: H04N1/403
Filed: 1992-07-13
Abstract: PURPOSE:To considerably accelerate error diffusion processing by decreasing the number of times of access accessing a storage device just once for possessing error distributed from picture elements belonging to a preceding line. CONSTITUTION:Binarization error HG generated at a picture element P0 is distributed by multiplying a coefficient 1/4 to picture elements P1 and P5 respectively adjacent to the respective downstream sides of a main scanning direction RM and a sub scanning direction RS at the time of reading the image of the picture element P0 with an image sensor. On the other hand, the error is distributed by multiplying a coefficient 1/8, for example, to two picture elements P3 and P4, for which the main scanning direction RM is positioned on the upstream side concerning the picture element P1, and a picture element P6 adjacent to the picture element P5 on the downstream side of the main scanning direction. In the case of error diffusion processing to an attention picture element A, the error distributed from peripheral picture elements is added to the density data of the attention picture element A, binarizing processing is performed corresponding to this result, and the result of gamma correction to preceding line data is obtained. Thus, density adjustment processing and gamma correction processing can be simultaneously performed.

Title: Method and apparatus for verifying dynamic signature
Inventor: EINAA ERU ASUBO
IPC: G07C9/00
Filed: 1986-09-08
Abstract: Orthogonal output signals generated by a stylus (40), are normalized such that they are insensitive to the rotational position of the stylus (40) with respect to the writer's grip. Pressure measurements made by strain gauges (52) on a flexible diaphragm (50) in the stylus (40) are sampled at discrete intervals and a normalization angle of writing movement is calculated, representative of the average direction of the signature, by a processor (60). Each sample of orthogonal output signals is then assigned a vector length which is rotated by the normalization angle. The normalized samples are utilized to perform signature analysis by a comparison with a stored reference signature set of normalized orthoganal samples carried out by the processor (60).
