摘要： According to at least one embodiment, a multi-angle multi-time-point method authenticates 2D objects with high confidence by sampling the object through space and time while being capable of automatically authenticating and inputting object information. Some embodiments further enhance authentication confidence by utilizing unique characteristics of hologram and/or personal photo. While this method possesses artificial intelligence comparable to human's in term of authenticating and extracting information from 2D objects, it's also highly efficient and can achieve real-time performance (e.g., processing 5 frames per second) on ordinary personal computers. Structural information is first extracted from a 2D image to reduce processing time for subsequent steps as more operations on the 2D images are avoided. By employing similar divide-and-conquer strategy according to a binary search algorithm for 1D data array, a Visual Binary Edge Search Algorithm is applied to a 2D image application.

摘要： Traditional streaming sequentially downloads content fragments one by one from one CDN. The disclosed streaming method concurrently downloads content fragments from multiple CDNs. It first creates a sequence of bundles of fragments, and then downloads a subsequent bundle by spreading requests to download the fragments within the bundle to multiple CDNs simultaneously with each CDN acting as a channel to download a different fragment. Depending on business needs, various request dispatching strategies can be deployed. When there is a volume based pricing contract with a CDN, a dispatch strategy is to send more requests to the CDN in order to reach contract volume therefore reduce unit cost. Another strategy is to send the request for the earliest fragment to the fastest CDN in order to reduce latency and possibility of buffer underrun. Fault tolerance can be provided by re-routing a request failed at a CDN to another CDN.
