摘要： Disclosed is an image processing apparatus in which vector data from which noise has been removed and amount of data reduced can be generated in ideal fashion with regard to an illustration area selected from a document image. The document image is input to the apparatus and is segmented into a plurality of areas. A clip-art image is selected from these areas and a plurality of clusters are generated with regard to this image area. When a small area included in the plurality of clusters is determined as a noise, the noise is eliminated by combining the small area with a adjacent cluster. After noise is removed, the cluster group eventually obtained is converted to vector data.

摘要： An image processing apparatus in which image data is input, a generator generates area information and a processor processes the image data in accordance with the area information. The generator includes a first generator for generating the area information by using area data for each pixel having a predetermined size stored in a memory, and a second generator for generating the area information by use of a central processing unit (CPU) without using the area data stored in memory. A selector selects one of the area information generated by the first and second generators so that the processor can process the image data in accordance with one of the area information generated by the first and second generators.

摘要： An image processing apparatus, image processing method, and program which enable generation of vector data capable of replicating a clipart region of a raw image as faithfully as possible are provided. To accomplish this, a raw image is segmented into region images according to attributes. From the segmented region images, a region image having a predetermined attribute is cut out from the raw image. At least one representative color which configures the predetermined region image is decided based on an appearance color of the cut out predetermined region image. A color image having the decided representative color is extracted from the predetermined region image. A contour line of the extracted color image is extracted. An edge image within the predetermined region image is extracted. The extracted contour line is corrected based on the extracted edge image. Using the corrected contour line, vector data of the predetermined region image is generated.

摘要： This invention has as its object to provide an image coding method which can efficiently encode image data by fully utilizing a two-dimensional correlation of an image. A block matching means searches for a block position corresponding to a minimum absolute value sum of differences of a pixel block to be encoded from already encoded pixel blocks. The searched block position information is encoded by an encoder, and the searched inter-block difference value is Huffman-encoded by another encoder. A code generator generates encoded data using these codes.

摘要： An image processing apparatus is provided which can shape codes and omit buffers at a decoding side as well as omit an image memory at an encoding side by providing code buffers for respective encoders. An image encoding apparatus for encoding image information in a hierarchical form includes encoders provided for respective hierarchies and code buffers provided after the respective encoders. Furthermore, it is possible to use a common code buffer memory for respective hierarchies at the encoding side. In such a case, by arranging so that a hierarchical tag can identify to which hierarchy a code belongs, a simplified encoding apparatus is provided.
