A transmission device divides image data into a plurality of regions on the basis of a similarity of pixels and transmits the image data and region representative points of the plurality of regions. A reception device receives the image data and the region representative points transmitted from the transmission device. The reception device generates region labels used for identifying the plurality of regions using the image data and the region representative points.

There is provided an information processing apparatus. A multidimensional input vector is input. For each dimension of the input vector, a function value of a single-variable function with an element of the dimension as a variable is derived, by referring to a lookup table indicating a correspondence between a variable and a function value of the single-variable function. A product of the single-variable functions approximates a function value of a multiple-variable function. For each dimension of the input vector, a product of the function value derived by the derivation unit and a predetermined coefficient corresponding to the dimension is calculated. A value calculated using the total of the products calculated by the product calculation unit for each dimension of the input vector is output as a classification index indicating a class of the input vector.

An image processing method includes sending test image data to a plurality of image recognition units configured to detect a recognition object from an image, setting an evaluation condition for evaluating a recognition result, evaluating a recognition result of the test image data by each of the plurality of image recognition units under the evaluation condition, and selecting from the plurality of image recognition units an image recognition unit to be used based on an evaluation result by the evaluation.

Image processing apparatus and image processing method for evaluating a plurality of image recognition processing units

An image recognizing apparatus which makes it possible to shorten waiting time before the start of image recognition processing for recognition objects requested by clients. A registering section registers designating information designating recognition objects in image data and a recognition termination condition for terminating recognition carried out by an image recognizing section, which are transmitted from each of the clients that have requested the right of use of the image recognizing section, in association with each of the clients. A client managing section causes the image recognizing section to carry out recognition based on the registered designating information for a client apparatus given the right of use, and carries out control to change the right of use to the next client apparatus when the registered recognition termination condition is satisfied.

An image recognition apparatus that recognizes an object related to a certain object in an image sequentially recognizes an object from the image in accordance with recognition-order information that indicates an object order in an object sequence including the certain object, the related object, and an object connected between those objects. The apparatus determines whether or not an object recognized in a current turn of recognition has a connective relationship with an extracted object obtained in a previous turn of recognition, and obtains the object that has been determined as having a connective relationship as an extracted object. Based on an object extracted by a repetition of the above processing, that is, recognition, connective relationship determination, and obtaining, in the above-described recognition order, the related object is associated with the certain object.

An image processing apparatus which is capable of suppressing an increase in the circuit size of buffers between data-processing circuits, thereby enabling an associated component thereof to be implemented by hardware. A position control unit sequentially shifts a position of a sub window image by a predetermined skip amount in a predetermined scanning direction, for scanning, and further repeating the scanning for skipped sub window images, after shifting a start position of the scanning, to thereby determine positions of all sub window images each as an area from a face image is to be detected.

A data compression method for executing encode commands for PackBits compression by a processor. The encode commands include a first command to obtain an encode processing state of the PackBits compression and control output of a control code (+1, &#x2212;2 etc.) based on the encode processing state, a second command to control output of input data (A to F) based on the encode processing state, and a third command to control output of a control command upon completion of the PackBits compression. In this arrangement, the PackBits encode processing can be performed at a high speed by the processor.

A data processing apparatus improves speed and efficiency of transfer of bit data, especially, multivalue data bit plane. For this purpose, a memoryholds four 8-bit multivalue data per 1 word, and bit plane coding processing is made by 4&#xd7;4 (=16) multivalue data (processing block). In a memory area, the most significant bit (bit) of respective multivalue data (datatoin FIG.) is collected in the order of multivalue data, and stored in one position (hatched portions in FIG.). Similarly, bitis collected from the respective multivalue data and stored in one position.
