Abstract: An image processing apparatus first forms an edge image of an input image using, for example, SOBEL operator, and performs a smoothing process on the formed edge image by using an average filter. Thereafter, the image processing apparatus calculates a difference between the edge image and the edge smoothed image, and binarizes the edge image based on the difference.

Abstract: An apparatus for detecting a person or the like from an image extracts candidates, which are considered to human body regions, from the image. Region likelihood probabilities of the respective candidates are obtained, and a human body likelihood of a collection of the candidates is probabilistically calculated using the region likelihood probabilities and correlations among the candidates. It is thereby possible to detect the person robustly against occlusion or change in photographic environment without increasing calculation cost.

Abstract: A moving robot first moves straight in a first forward path. When encountering an obstacle such as shelf, the robot makes a U-turn to move straight in a backward path located with a prescribed distance away from the first forward path. When encountering another obstacle, the robot again makes a U-turn to move straight in a second forward path extending in the same direction as that of the first forward path but located with a distance away from the backward path. When the robot exceeding the point of the U-turn in the first forward path is detected during running in the second forward path, presence of a region where the robot has not run yet is recognized, and running in that region is carried out thereafter.

Abstract: In a customer information management system a customer coming to a shop is image-sensed with a camera and the image information is used to automatically determine an attribute of the customer. Furthermore the image information is also referred to to count how often the customer comes to the shop, to determine whether the customer is a regular customer or a new customer. Furthermore there is also recorded information of customers leaving the shop without buying anything. Thus a customer attribute can automatically be determined and information can be improved in reliability, and a marketing strategy considering how often customers come to the shop, a marketing strategy for non-purchasers, and other similar strategies can also be developed.

Abstract: When a running vehicle moves backward and a right back portion of the robot, which is one end of it touches a wall, the robot is rotated to the left until a left back portion of the robot touches the wall. The angle of rotation .beta. at this time is measured and the value .beta./2 is represented by .alpha.. The robot is rotated to the right by the angle .beta.-.alpha.. Therefore, the robot is positioned perpendicular to the wall. Thereafter, the robot is moved backward until the back portion of the robot touches the wall. As a result, an apparatus for positioning the running robot relative to the wall is provided.

Abstract: In a signal processor for processing zeroth through (N-1)-th input signal elements into zeroth through (N-1)-th output signal elements, the input elements are initially stored, as memorized data, in respective memory addresses of a memory arrangement (11, 12) by a memory accessing arrangement which comprises a first address calculating arrangement (311, 321) for calculating a first address for the memory addresses. A distance indicating arrangement (312, 322) is for indicating an address distance from the first address among the memory addresses. By using the first address and the address distance a second address is calculated by a second address calculating arrangement (313, 323). A pair of stored data are read from the first and the second addresses as a pair of read data.

Abstract: In a processing circuit for successively accumulating a first predetermined number of products, each product is shifted in a barrel shifter (20) downwards by a second predetermined number of bits determined in relation to the first predetermined number and is successively added to a previous result of accumulation in an arithmetic/logic unit (ALU) (21) the first predetermined number of times to produce a final result of accumulation. The first result is shifted in a shifter (27) upwards by a third predetermined number of bits determined in relation to the second predetermined number. An overflow detector (26) monitors each result of accumulation to detect occurrence of an overflow in the ALU and the shifter to substitute either a positive or a negative maximum number for each result by an overflow corrector (25) on occurrence of the overflow. The substituted maximum number or the shifted final result is produced as an output signal.
