摘要： A method for analyzing images to generate a plurality of output features includes receiving input features of the image and performing Fourier transforms on each input feature. Kernels having coefficients of a plurality of trained features are received and on-the-fly Fourier transforms (OTF-FTs) are performed on the coefficients in the kernels. The output of each Fourier transform and each OTF-FT are multiplied together to generate a plurality of products and each of the products are added to produce one sum for each output feature. Two-dimensional inverse Fourier transforms are performed on each sum.

摘要： Checksum computation for video coding is provided that breaks the dependency between the color components of a picture in the prior art. More specifically, rather than computing a single checksum for a picture as in the prior art, a separate checksum is computed for each color component. Computing a separate checksum for each color component enables parallel computation of the component checksums. Methods are provided for computing three separate checksums after a picture is decoded. Methods are also provided for computing three separate checksums on a largest coding unit basis, thus allowing the checksums for a picture to be computed as the picture is being decoded.
摘要翻译：提供了用于视频编码的校验和计算，其破坏了现有技术中的图像的颜色分量之间的依赖关系。更具体地说，与现有技术相比，不是计算图像的单个校验和，而是为每个颜色分量计算单独的校验和。为每个颜色组件计算单独的校验和，可以并行计算组件校验和。提供了在解码图片之后计算三个单独的校验和的方法。还提供了用于在最大编码单元的基础上计算三个单独的校验和的方法，从而允许当图像被解码时计算图像的校验和。

摘要： A method is provided that includes receiving pictures of a video sequence in a video encoder, and encoding the pictures to generate a compressed video bit stream that is transmitted to a video decoder in real-time, wherein encoding the pictures includes selecting a picture to be encoded as a delayed duplicate intra-predicted picture (DDI), wherein the picture would otherwise be encoded as an inter-predicted picture (P-picture), encoding the picture as an intra-predicted picture (I-picture) to generate the DDI, wherein the I-picture is reconstructed and stored for use as a reference picture for a decoder refresh picture, transmitting the DDI to the video decoder in non-real time, selecting a subsequent picture to be encoded as the decoder refresh picture, and encoding the subsequent picture in the compressed bit stream as the decoder refresh picture, wherein the subsequent P-picture is encoded as a P-picture predicted using the reference picture.
