摘要： A method for updating a subset of a frame of an image is provided. The frame of the image is subdivided into a plurality of tiles. The method initiates with providing a fixed-size queue having a stationary last packet at a bottom of the fixed size queue. Then, a plurality of packets is stored in a time sorted order above the last packet, the plurality of packets corresponding to a frame of an image. Next, an updated packet is received, the updated packet corresponds to a previously received packet of the plurality of packets. Then, the previously received packet is replaced with the updated packet while maintaining the time sorted order. Replacing the previously received packet includes: identifying the previously received packet adjusting any pointers pointing at the previously received packet to point at a packet below the previously received packet; and moving the previously received packet to a top of the fixed size queue. An apparatus and system for distributing packets through a multi point dispatcher between multiple clients is also provided.
摘要翻译：提供了一种用于更新图像帧的子集的方法。图像的帧被细分成多个瓦片。该方法通过在固定大小队列的底部提供具有固定最后一个分组的固定大小的队列来启动。然后，以最后一个分组之上的时间分类顺序存储多个分组，多个分组对应于图像的帧。接下来，接收到更新的分组，更新的分组对应于先前接收的多个分组的分组。然后，将先前接收的分组替换为更新的分组，同时维持时间排序顺序。替换先前接收的分组包括：识别先前接收的分组，其调整指向先前接收的分组的指针，以指向低于先前接收的分组的分组; 并将先前接收到的分组移动到固定大小队列的顶部。还提供了一种用于在多个客户端之间通过多点分派器分发分组的装置和系统。

摘要： A technique that reduces the size of an existing JPEG file or set of DCT coefficients to satisfy a certain bit budget by setting to zero coefficients whose magnitude is below a certain threshold and which occur after a certain ordinal number in the zig-zag scan. The cutoff ordinal number is chosen using a clever savings calculation strategy. This strategy is implemented by filling appropriate savings values in an array of savings values, Savings[1], . . . , Savings[63]. The value Savings[n] is exactly the number of bits saved by reducing the thresholding cutoff ordinal number from n +1 to n. When a non-zero coefficient is set to zero, bits are saved because two runs of zeros (the one preceding it and the one following it) get combined into a single, longer run of zeros. The exact number of bits saved can be calculated by adding the bits needed to code the previous and next runs, and subtracting the bits needed to code the combined run. Some special conditions (runs longer than 16 and end-of-block conditions) need to be carefully factored into the computation.

摘要： In an example embodiment, a calibration module in a projector platform establishes an initial configuration of settable exposure attributes for a digital camera. The calibration module projects a preview image onto a surface and captures the projection of the preview image with the digital camera and receives input from a user identifying regions of interest in the capture of the preview image. Next the calibration module projects an exposure image onto the surface. The calibration module then computes a final configuration of exposure attributes for the digital camera by iteratively: (a) capturing the projection of the exposure image with the digital camera; (b) measuring descriptive statistics relating to the color channels of pixels in the regions of interest in the capture of the exposure image; (c) evaluating the descriptive statistics with an evaluation function determined by a calibration process; and (d) establishing a revised configuration of exposure attributes.

摘要： In an example embodiment, a system for creating a display from multiple projectors receives as an input a source pixel derived from an image to be displayed. The system generates a scalar-adjusted pixel by applying a scalar for an adjustment range to each channel value in the source pixel, where the scalar depends on whether the source pixel is gray or color. The system modifies each channel value in the scalar-adjusted pixel according to a luminance adjustment curve for a projector, where the luminance adjustment curve depends on whether the source pixel is gray or color. The system generates the luminance adjustment curve from captured calibration images by: (1) creating an interpolated response curve; and (2) generating and inverting a median difference curve based on the interpolated response curve for the projector and the interpolated response curves for the other projectors in the system.

摘要： First, a delivery delay, i.e. the time it takes for a content to be captured and a representative frame made available (i.e. delivered), is determined. Second, a video capture interval, i.e. a minimum time delay requirement between stable captured content frames, is determined. In other words, the recycle time-period after which it is safe to change frame content during a capture interval without impacting a prior stable video frame in the pre-delivery stage is determined.
