A method is provided for optimizing an objective measure used to estimate mean opinion score or naturalness of synthesized speech from a speech synthesizer. The method includes using an objective measure that has components derived directly from textual information used to form synthesized utterances. The objective measure has a high correlation with mean opinion score such that a relationship can be formed between the objective measure and corresponding mean opinion score. The objective measure is altered to provide a different function of textual information derived from the utterances so as to improve the relationship between the scores of the objective measure and subjective ratings of the synthesized utterances.

A security system with a Pan / Tilt / Zoom Camera and maskable motion detection is disclosed. At selected fields of view of the P / T / Z camera, masks are created to mask, from motion detection, select sub-areas within the selected field of view. The mask created for the selected view may be saved in memory. The saved mask may be recalled and reapplied to the motion detector whenever the P / T / Z camera is repositioned to the field of view corresponding to the saved mask. The commands required to reposition the camera to each selected field of view may also be saved. The mask and repositioning commands can be associated with each other, so that selecting a target view corresponds to selecting the commands to position the camera to that view, as well as the mask to be applied for this view.

The invention relates to a system and a method for the generation of 3D images of a moving joint (1). A rotational X-ray device (10) generates projections of said joint from different directions while the simultaneous periodic movement of the joint (1) is recorded by a monitoring device (20). The generated X-ray projections are then classified according to the phase of joint movement to which they belong, and 3D images are reconstructed from X-ray projections of each class. Thus a 3D movie of the joint movement can be produced and shown on a monitor. The monitoring device (20) may particularly be realized by an apparatus that allows the forced movement of the joint (1) in synchronization with the generation of X-ray projections.

The invention relates to a video encoder (201) for encoding a video signal. The video encoder comprises a segmentation processor (207) which divides the picture into picture regions. Preferably, picture regions having a high degree of flatness or uniformity are determined in this way. A characteristics processor (209) determine a spatial frequency characteristic for each picture region, and a coding controller (211) selects an encoding block size, such as a prediction block size for motion estimation, in response to the spatial frequency characteristic. An encode processor (213) encodes the picture using the selected encoding block size. Specifically, increasing block sizes are selected for increasing degrees of uniformity or flatness indicated by the spatial frequency characteristic. Thereby, an increasing proportion of high frequency components and a consistent choice of encoding block sizes are maintained, and thus the coding artefacts from many encoders having variable prediction block sizes is reduced. The invention is particularly suitable for H.264 and similar encoders.

A video coding method for surveillance videos allowing some regions of the scene to be encoded in an almost lossless manner. Such Regions of Interest (RoI) can be determined a priori or they can be automatically determined in real-time by an intelligent system. The user can set high priority in such regions a priori or the intelligent video analysis algorithm can automatically assign some windows a higher priority compared to the rest of the video. In a preferred embodiment, this can be achieved by canceling the motion estimation and compensation operations, and then decreasing the size of the quantization levels during the encoding process in the RoI. The present inventions can produce MPEG compatible bit-streams without sending any side information specifying the RoI.

Encoding and decoding of property data, such as colour values, associated with vertices forming 3D objects. From an analysis of connectivity data, a spiral-like scanning path of the vertices within the 3D model is obtained. The colour values are mapped to a 2D image, each attribute value to a pixel. Next, the mapped 2D image is encoded. To increase redundancies in the 2D image, the spiral-like path is split into path segments, each forming a turn in the spiral; each path segment is assigned to a respective line of the 2D image; and the colour values of each path segment are mapped, in the same order, to the respective line of the 2D image. Successive lines in the 2D image thus contain the colour values of neighbouring vertices in the 3D object, and a better encoding can be achieved.

Prognostic and diagnostic information is determined about an investment portfolio through perturbing the investment portfolio with allocations to other sectors and reviewing the performance of the perturbed investment portfolios using historical data, and combining that with other factors. Relationships between one's investment portfolio and other assets, rights or liabilities can be identified by creating several modified portfolios each of which comprise a mix of the original investment portfolio and one or more of the other assets, rights or liabilities. The performance of these modified portfolios, as compared to the original portfolio over a historical period, indicates the correlation (or lack thereof) between these other assets, rights or liabilities and one's investment portfolio. By identifying these correlations, one can then take any desired action to modify one's portfolio to obtain the desired results.
