Abstract: A video processing method, an electronic device and a storage medium are provided. The method includes: a target frame is determined in a video to be processed; at least two first energy images corresponding to the target frame are determined based on at least two preset macro block sizes respectively, each first energy image represents alternating current energy of first macro block(s) corresponding to a respective macro block size and the first macro block(s) are obtained by segmenting the target frame based on the respective macro block size; a first energy map corresponding to the target frame is determined based on the first energy images, the first energy map represents energy distribution in the target frame; and an adaptive quantization parameter corresponding to the target frame is determined based on the first energy map and the target frame is encoded using the adaptive quantization parameter.

Abstract: In one aspect, the invention comprises acquiring background data regarding securities positions and regarding real-time pricing data; performing calculations regarding intermediate measures of performance of the securities; receiving configuration data for a portfolio of securities and one or more data requests, at least one of the data requests comprising a request for a value at risk report regarding the portfolio; and providing a value at risk report based on a Parkinson's volatility estimation. In another aspect, the invention comprises displaying a tree structure display in a first portion of a graphical user interface display; in response to a user selecting an item from the tree structure display, displaying a corresponding listing in a tabular display in a second portion of the graphical user interface display; and in response to the user selecting a listing in the tabular display, displaying a corresponding item in the tree structure display.
