摘要： A content delivery method directs a request by a client for an object to a first server in a content delivery network (CDN), regardless of whether the first server has the requested object. If the first server has the requested object, then it is served to the client from the first server; otherwise, the first server redirects the client request to a second server in the CDN to handle the request. The second server may be a peer server of the first server. The first and second servers may be edge servers in the CDN.
摘要翻译：内容递送方法将用于对象的客户端的请求定向到内容递送网络（CDN）中的第一服务器，而不管第一服务器是否具有所请求的对象。如果第一个服务器具有所请求的对象，则从第一个服务器向客户端提供服务; 否则，第一个服务器将客户端请求重定向到CDN中的第二个服务器来处理该请求。第二服务器可以是第一服务器的对等服务器。第一和第二服务器可以是CDN中的边缘服务器。

摘要： A method, system and computer program product for managed object replication and delivery redirects, directly or indirectly, a client's request for an object that is not available at a best or optimal handling edge server of a network to a parent server that has the requested object. So, where the requested object is not available at the handling edge server, the client's request is redirected directly to the parent server that can provide the requested object to the client or indirectly via one or more parent servers to a parent server that can provide the requested object to the client. The method, system and computer program product further intelligently replicates the object to the edge server if the object is popular enough. Likewise, an object is removed from an edge server when it is no longer popular. All redirection and replication operations are preferably transparent to the end-user and do not degrade the quality of service.
摘要翻译：用于托管对象复制和传递的方法，系统和计算机程序产品直接或间接重定向客户端对网络的最佳或最优处理边缘服务器不可用的对象的请求，该对象具有请求对象的父服务器。因此，在请求的对象在处理边缘服务器处不可用的情况下，客户端的请求被直接重定向到可以向客户端提供所请求的对象的父服务器，或者通过一个或多个父服务器间接地传递到父服务器，父服务器可以提供请求客户的对象。如果对象流行得足够，方法，系统和计算机程序产品将智能地将对象复制到边缘服务器。同样，当边缘服务器不再受欢迎时，对象将从边缘服务器中删除。所有重定向和复制操作对于最终用户来说最好是透明的，并且不会降低服务质量。

摘要： A learning-based visual attention prediction method is disclosed. The method includes a correlation relationship between the fixation density and at least one feature information being learned by training, followed by a test video sequence of test frames being received. Afterward, at least one tested feature map is generated for each test frame based on the feature information. Finally, the tested feature map is mapped into a saliency map, which indicates the fixation strength of the corresponding test frame, according to the correlation relationship.

摘要： An autofocus method for obtaining clear images characterized by: adjusting the lens position with an initial dataset of focus values to obtain a estimated lens position; moving the lens to the estimated lens position and acquiring the corresponding focus value; determining whether the estimated lens position is sufficiently proximate to the prior estimated lens position, wherein, if it is, the autofocus process stops, and, if not, repeating the above-described steps until a lens position having an optimal focus value is obtained, thereby obtaining the clearest image with increased focusing speed and reduced time of lens movement and without the need of empirical parameters.

摘要： A perceptual-based video coding method provides a perceptual-based rate-distortion (R-D) curve as a predictive R-D curve. The Lagrange multiplier for a current frame is then determined by deciding a slope, with sign reversed, of a tangent to the predictive R-D curve at a current point that is on the predictive R-D curve and closest to a previous R-D point of a previous encoded frame. The current frame is then encoded according to the determined Lagrange multiplier.

摘要： Data which represents an animation sequence of a three dimensional object at a series of discrete time frames is compressed by identifying characteristic features of the object; generating a quadrangular mesh representation of the object, whereby the object is mathematically defined by dividing it into one or more regions and hierarchically representing each region by a mesh, each mesh including three coordinate matrices which define the positions of nodes within the mesh; selecting from the mesh representation of the features a set of animation parameters which are capable of specifying changes in the mesh corresponding to the animation of the object; compressing each region mesh by applying pyramid progressive coding to the coordinate matrices for the mesh; storing the initial values for the animation parameters at the beginning of the animation sequence; and, at each time frame after the beginning of the animation sequence, estimating the current values of the parameters and compressing each parameter by estimating the change in the value of the parameter by subtracting its stored value for the previous time frame from its current value, quantizing the estimated difference, applying entropy coding to the quantized difference and updating the stored value with the decoded value.
