Abstract: A method of processing an original image for projection on a projection screen by a projector, comprising performing pixel interpolation between pixels of a first image associated with the original image and pixels of a second image associated with a pixel grid of the projector, wherein at least one of the first image and the second image has a pixel resolution greater than the resolution of, respectively, the original image and the pixel grid. Embodiments of the invention provide pixelization artifacts reduction in displaying high-definition videos with flexibility and low complexity.

Abstract: A maximum hypersphere is created in the feature space according to support vectors, wherein the support vectors are one or more feature vectors in a feature space. A center of the created maximum hypersphere is calculated according to the support vector(s). A decision hyper sphere is created with the same center as the calculated center of the created maximum hypersphere. Feature vector(s) are classified within the decision hypersphere, as positive feature vector(s). False positive rate is kept to a predetermined level to provide effective object detection.

Abstract: If the temperature of a fixing unit is not stable when automatic gradation correction is performed, an error occurs in gradation correction when a chart for gradation measurement is output. An image forming apparatus of the present invention is characterized by including a unit configured to transfer a toner image based on image data onto a sheet, to pass the sheet through a fixing unit, and to output a first chart, a unit configured to create a conversion table for gradation correction using a value obtained by reading the output first chart, and a stabilization processing unit configured to stabilize the fixing unit by outputting a second chart before outputting the first chart when creation of the conversion table for gradation correction is instructed, wherein the stabilization processing unit outputs the second chart in a number of sheets specified in advance by a user.

Abstract: An image processing apparatus includes a processing unit configured to generate a processed image by processing a plurality of band limit signals based on a parameter for adjusting the band limit signal, and a control unit configured to control the parameter so that an amplitude response of the processed image with respect to an original image is to be a predetermined value or more.
