A tampering judgement system is provided which is capable of easily checking whether or not a printed document has been tampered. An image feature information extracting section extracts image feature information from a document image. An image feature information embedding section gives image feature information integrally as original image feature information to a document and a document image output section outputs the information as a printed document. When the printed document is given to t...

The invention is a lamp quality judgement apparatus and judgement method which judge quality by detecting the state of gas sealed in an electric lamp such as a gas-filled incandescent lamp, etc. in which gas with an Argon-Nitrogen mixture as its main component is sealed. More particularly, a lamp in which such gas is sealed is classified as a good product or as a bad product by imposing a high DC voltage or a high AC or pulsed voltage with a comparatively low frequency of 1 kHz or less across th...

A video image is obtained of an object and divided into a matrix of horizontal and vertical zones. The matrix is scanned sequentially and those zones determined to have defects stored. The position of each of the stored zones are determined by the distance horizontally and vertically from a base comprising the zone indicated preceding in the scan.

A method of generating a collaborative judgment for use in coding a symbol is described. One method includes generating multiple probability estimates for a symbol to be coded, selecting an exaggeration exponent and weighting information indicative of weighting between the probability estimates, and combining the probability estimates into the collaborative probability estimate based on an exaggeration function using the exaggeration exponent and the weighting information.

An improved monaural signal judgement circuit which is capable of judging whether or not an input signal is monaural when signals from a television, a video cassette tape recorder, an audio cassette tape recorder, a compact disc player, or the like are inputted to the monaural signal judgement circuit and of converting the process into a pseudo stereo function when the input signal is monaural, which includes a wave form shaping circuit for separately wave-form-shaping a left-side signal and a r...

In a judgement support system and method, essential items to be necessarily judged and optional items to be optionally judged by a user are displayed on a menu screen, thereby allowing a judgement through intuitive knowledge of the user. After judgement results of all essential items have been inputted, the system is allowed to stop its operation. When a judgement result is inputted, an evaluation of the judgement is outputted in accordance with a predetermined rule. The evaluation includes upda...

This invention relates to a system which improves an operation speed and accuracy of judgement when the posture of an object component parts is judged by an image processor. This system determines a combination of parameters used for the posture judgement at the time of the preparation of standard data, classifies the types in accordance with the parameter combinations and makes processing for a parameter combination designated for each type at the time of recognition, thereby judging the postur...

A vehicle running condition judgment device for accurately detecting a change in a road surface condition and a vehicle's limit running condition. With substitution of respective tire characteristics and a detected state quantity into a vehicle motion model, vehicle slip angles are estimated for respective assumed road surface conditions. Based on the current state quantity and the last estimated vehicle slip angle, currently estimated vehicle slip angles for the respective assumed road surface ...

A defect judgement processing method and apparatus which can optimize image processing and defect judgement parameters for a detection image cut out by each inspection window to avoid erroneous judgement and defect missing and to realize reliable defect judgement. An image data generator cuts out ranges indicated by a plurality of predesignated inspection windows from a detected image and stores them in a memory, a window data generator generates window data having inspection conditions attached...

A camera includes a feeder for feeding a film having magnetic recording portions, a reader for magnetically scanning magnetic recording portions to generate scan signals, and a judger for judging whether or not a magnetic recording portion has been recorded with magnetic data by comparing scan signals with a threshold value, and a warning device for generating a warning when judgment of the judger is impossible. This apparatus can ensure more accurate judgment as to whether a signal picked up fr...
