Methods, and apparatus implementing methods, including computer program products, for merging images of segments of a view. Methods include: receiving, from a network, a first image representing a first segment of the view and a second image representing a second segment of the view; determining the position of the second segment of the view relative to the first segment of the view; blending the first image with the second image based on the determined position of the second segment relative to...

This invention provides an image processing apparatus for executing padding processing at a high speed. For this purpose, the image processing apparatus of this invention is an image processing apparatus for processing image data on the basis of shape information, which includes a left propagation processing section (121) for propagating, of a plurality of pixel data which construct one-dimensional image data, pixel data specified by shape information to the left, a right propagation processing ...

To compose an image from a plurality of partially overlapping images, both positional movement and perspective transformation are performed using pyramidal data structures. After the positional movement is determined for a unit block of one partially overlapping image to match a corresponding block, a set of perspective transformation parameters is determined based upon the positional movement. The partially overlapping images are composed into a single image while the partially overlapping imag...

An apparatus, program product and method for rotating image data using a block-based approach, wherein for each of a plurality of blocks of image data that define an image, a translation vector is applied to the block to translate the block a desired angle of rotation about a rotation point, e.g., to translate an anchor position for the block from a source point to a destination point. In addition, the image data within the block is rotated according to the desired angle of rotation, such that w...

Automatic vision system object indexing and image database query system using both path-dependent and path-independent features of moving objects within a sequence of images. Feature vectors of both average over frames of an object traversing the field of view plus average over blocks of a grid for a path association. Color histograms may be an included feature.

An image reading apparatus having a visible light source for emitting visible light, an invisible light source for emitting invisible light, an imaging optical system for irradiating a document by these light sources to form optical images of the document, and a CCD for photoelectrically converting the optical images of the document turns on the visible light source to acquire a visible light image signal by the CCD. Then, the apparatus turns on the invisible light source to acquire an invisible...

This invention is a method dedicated to pseudo-invariant features retrieval and, more particularly, applied to content-based copy identification. The range of a query is computed during the search according to deviation statistics between original and observed features. This approximate search range is directly mapped onto a Hilbert's space-filling curve allowing an efficient access to the database. Such a method is sublinear in database size and does not suffer from dimensionality problems.

The present invention provides for visual enhancement of text. A text area is selected. A plurality of non-identical images of the text area are captured. Background information is removed from these images. The contrast characteristics of text area of the plurality of images are increased. The contrasted images are combined so as to increase their effective resolution. In an alternative embodiment, the text picture is broken up into a plurality of component colors, and these colors are then sha...

An image reading system is provide, which includes a reading apparatus for reading an original, and a host computer. The host computer includes a storage unit, a reading setting selection unit for selecting a reading setting in the reading apparatus, a setting changeing unit for changing the reading setting if the size of the image data is larger than the available area in the storage unit, a change content notification unit for notifying users of change contents before the setting change unit c...

Methods and apparatus for processing n-dimensional digitized signals with a foveal processing which constructs a sparse representation by taking advantage of the geometrical regularity of the signal structures. This invention can compress, restore, match and classify signals. Foveal coefficients are computed with one-dimensional inner products along trajectories of an n-directional trajectory list. The invention includes a trajectory finder which computes an n-directional trajectory list from th...
