Abstract: A facility for event failure management is provided, which includes providing a failed event database containing failed event information relating to failed events and one or more components associated with each of the failed events. Upon modification to a component associated with a failed event, the failed event is retried. Based on a result of retrying the failed event, failed event information of the failed event database is updated. The failed event database may therefore be dynamically and/or automatically updated so that it contains up-to-date and appropriate information for predicting and/or managing event failures.

Abstract: A computer hardware system for synchronization of data between a first data system and a second data system includes an event propagation processor. Both data systems are modeled as a collection of representation state transfer (REST) resources. The event propagation processor is configured to integrate data between the first and second data systems for events about data changes in the data systems. The processor includes an adaptation layer in the form of an HTTP (Hypertext Transfer Protocol) facade to represent REST resources. The adaptation layer includes a provider component configured to provide access to data resources in one of the data systems, and an initiator component configured to emit events corresponding to data changes in one of the data systems.

Abstract: In a messaging system, pruning messages from a data store according to similarity of topics and the number of requests for the individual messages and the time intervals between requests of messages of similar topic.

Abstract: Disclosed is a method, apparatus and computer program for sampling a data feed of messages at regular time intervals. A current sample point is identified. A time interval is also identified which is defined by the current sample point and at least one of the previous sample point and the subsequent sample point. At least one message is selected to associate with the current sample point. The selection is made from the identified time interval. The selected message(s) is then associated with the current sample point.

Abstract: A method of removing a moving part from a video stream image comprising obtaining a plurality of frame-series images of the scene, each image comprising a moving part and a static part; comparing the plurality of frame-series images to identify parts of the scene that are static for a plurality of frames; and building part of the scene identified as static.

Abstract: A method for segmenting video data into foreground and background portions utilizes statistical modeling of the pixels. A statistical model of the background is built for each pixel, and each pixel in an incoming video frame is compared with the background statistical model for that pixel. Pixels are determined to be foreground or background based on the comparisons. The method for segmenting video data may be further incorporated into a method for implementing an intelligent video surveillance system.

Abstract: Provided are methods, apparatus and computer program products for switching between data streams. The data streams include a matching set of data items in a consistent sequence. One data stream may be a superset of the other, and which data stream is running ahead of the other may not be known in advance. It is desired to synchronize the data streams so that a data receiver can be switched from a first to a second data stream without loss of data. For a time period of interest, characteristics of a first data item on one stream are compared with characteristics of each latest-received data item on the other stream until a match is identified. This match is used to identify a synchronization point for the switch between data streams.
