A method of determining the three-dimensional position of an object in a specific position with respect to a predetermined standard position includes storing position data representative of a distinctive part of the object as if the object is virtually located in a predetermined standard position, formularizing a relation between the specific and standard positions in terms of a standard three-dimensional co-ordinate system as an equation including a positional deviation as an unknown parameter, and determining a restrictive condition for the position of the distinctive part of the object located in the specific position. The equation is solved under a condition in which the position of the distinctive part satisfies the restrictive condition to find a positional deviation.
A method and apparatus in a data processing system for processing perspective transformations. An estimate of a depth coordinate is obtained. A determination is made as to whether the estimate is sufficiently accurate for the perspective transformation. An algebraic operation is performed on the estimate if the estimate is insufficiently accurate for the perspective transformation, wherein the algebraic operation increases the accuracy of the estimate.
A fax routing system and method using a standard fax machine and personal computer. The telephone number is decoded from the telephone number dialing which is generated by the fax machine. This number is looked up in a table. If a corresponding Internet address is found, the fax is downloaded from the fax machine, converted into a computer file, and sent to the recipient via his Internet address. If a corresponding Internet address is not found, the decoded number is dialed on a telephone line and, thereafter, the telephone line is connected to the fax machine for normal fax delivery.
The orientation of a camera associated with a first image is determined based on a shape of a perimeter of a corrected version of the first image. The corrected version of the first image has less perspective distortion relative to a reference image than the first image. The shape of the perimeter of the corrected version of the first image is also different from the shape of the perimeter of the first image. The first image is then projected onto a surface based on the orientation of the camera.
Methods and apparatus for shifting perspective in a composite image derived from a plurality of images including a first image as a center of projection, and a modified version of a second image that is corrected for perspective distortion relative to the first image. A user input specifies a change in perspective to make the second image the center of projection. In response, a transformation is determined for mapping reference points in the modified version of the second image to reference points in the original, uncorrected second image. The transformation is applied to each of the plurality of images in the composite image, and the transformed images are merged to form a second composite image that has the second image as its center of projection. The methods and apparatus can be implemented as an interactive tool capable of changing perspective based on a single user input.
Methods, systems, and apparatus, 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 the first segment to form a panoramic image of the view; and transmitting the panoramic image over the network.
