Abstract: The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map but not effective at presenting local detail. In contrast, street -side images show excellent detail but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps and can also display objects/features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable.

Abstract: A method for replacing parts of a digitally coded picture (11) is proposed. The digitally coded picture (11) may correspond to a sub-picture which is displayed on the screen of a television set (10). In the method, each line of the picture (11) is run length-coded.

The replacement of the data for the run length coding words is carried out in a memory device (51). The replacement is possible in a simple manner by virtue of the fact that the original part of a line of the picture and the new part of the line of the picture have the same number of data units. Moreover, a device for carrying out the method is also proposed.

In addition, an integral value calculating section 40 divides the change C' by the difference F-B to integrate the result obtained by divisional operation to thereby determine key signal .alpha.. As a result, precise key signal can be obtained in this invention.

Abstract: A method and system are provided for capturing and compressing an original uncompressed video signal which enables decoding and reversible reconstruction of a decompressed version of the original video signal. The system includes an input for receiving a signal indicating a special effect operation by which a first frame of a video signal is irreversibly transformed to a special effect frame.

The information indicates a special effect operation which can be performed on decompressed pixel data of the first frame to produce a special effect frame (e.g., the information can include a separate indicator specifying a specific operation or the information by its mere presence can indicate the special effect operation). The system also includes a processor for compressing pixel data of the first frame.

Abstract: Static fade in a digital video image is detected. A difference in luminance intensity is determined for correspondingly positioned pixels in successive images. A variance in the difference is determined, and then normalized according to a mean squared value of the difference to provide a fade index J.sub.n. The fade index is compared to a fade threshold, e.g., 0.9, to determine if a fade is indicated. Optionally, a check may be made to verify that a static fade is indicated by comparing the mean squared value of the difference to a motion threshold. The technique is suitable for both frame mode and field mode video sequences. When the digital images include field mode video, where each image has first and second fields, a fade index is determined separately for each field, and an overall fade index is obtained by averaging the fade indexes from each field. A scheme for detecting static fade on a macroblock by macroblock basis is also presented.

In a fourth step, the luminance pixel values are summed for the pixels in each field band of the current frame. In a fifth step, each respective field band sum and field sum of the current frame is compared with that of the previous frame in the video input sequence. In a sixth step, detection of whether or not a fade has occurred is provided, based upon the comparison in the fifth step. In a seventh step, the encoding algorithm is adjusted if a fade has occurred.

Abstract: A method for replacing parts of a digitally coded picture (11) is proposed. The digitally coded picture (11) may correspond to a sub-picture which is displayed on the screen of a television set (10). In the method, each line of the picture (11) is run length-coded. The replaceable parts of a line of the picture are run length-coded separately. The part which replaces the replaceable, original part of a line of the picture (11) is run length-coded in such a way that it has the same number of data units (data bytes) as the original part of this line of the picture (11).

The replacement is possible in a simple manner by virtue of the fact that the original part of a line of the picture and the new part of the line of the picture have the same number of data units. Moreover, a device for carrying out the method is also proposed.
