摘要： An image processing apparatus can generate a vector sequence representing each color region of a color image. The image processing apparatus divides the image into plural regions based on attribute information of the image, and extracts region boundary information relating to a boundary line between different regions. The image processing apparatus generates inter-edge point vector data for each boundary connecting a first edge point to a second edge point corresponding to intersections of boundaries between neighboring regions, based on the extracted region boundary information. The image processing apparatus identifies one or more inter-edge point vector data representing a boundary of each divided region based on the generated inter-edge point vector data, and generates individual region vector data.

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, 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： Although methods employing chain codes or Fourier descriptors are known for calculating an outline similarity between a model image and an object image, these methods are difficult to achieve detection of both an approximate similarity and local similarity. In view of this, according to the present invention, wavelet transformation is performed on outline points of an object image, and similarity calculation is performed on a plurality of model images with the use of a low frequency component of the transformation result. Only the model image, having a close agreement in matching processing, is subjected to similarity calculation using a high frequency component of the transformation result. By virtue of this processing, similarity calculation can be performed at high speed with high precision.

摘要： An analyzer estimates the time for rendering image data based on the number, types, etc., of rendering commands, stored in an intermediate memory, and determines whether or not there is a possibility of overrun. If there is the possibility of overrun, image data of respective bands formed in a band buffer are sequentially compressed and stored into a compressed image memory. When the image data for one page has been stored, the data in the compressed image memory is sequentially expanded and supplied to a printer engine. This avoids failure of image output due to overrun, while reducing the capacity of the image memory.

摘要： There is provided an image encoding method in a facsimile apparatus or an image filing apparatus as an image communication apparatus. In this method, a color image signal which is expressed by a plurality of color component signals to be encoded is input, the input color image signal is converted into a bit stream signal, and the bit stream signal is encoded by prediction encoding. A parameter for the prediction encoding is changed in accordance with the color image signal to be encoded. The encoding operation is executed adaptively to the color image signal to be encoded. By virtue of bit stream converting the binary color signal, efficient encoding using the color correlation can be executed and an increase in data amount is prevented. By encoding the bit stream signal using a dynamic arithmetic code, a binary color image can be efficiently encoded.

摘要： This invention can play back a smooth moving image in both normal and slow playback modes in consideration of the human visual recognition level, even when moving image data to be decoded (played back) is recorded (encoded) at a high frame rate. To this end, in this invention, respective frames, which form a moving image at 60 frames/sec, are compressed to be independently decodable. In the normal playback mode, since frames are played back using one of two frames (decimating one of two frames), a moving image is played back at 30 frames/sec which can assure sufficiently high image quality as a moving image. On the other hand, in the slow play back mode, since the number of frames to be decimated is set to be zero, and 60 frames are played back for 2 sec, a moving image is played back at the same frame rate of 30 frames/sec as that in the normal playback mode.
