Segment Tree is a powerful data structure in programming, that is why it can still be optimized way more. In this blog I will explain one optimization that can make a basic segment tree slightly faster and easie
The proposed algorithm in this article has four steps in total, which starts with the matching cost computation using census transform, cost aggregation utilizes segment-tree, optimization using winner-takes-all (WTA) strategy, and post-processing stage uses weighted ...
The parallel implementation is an optimization of bottom-up tree. Probably you all know how bottom-up implementation looks like, but I'll cite the main idea nevertheless to show the difference between bottom-up and parallel implementations: In bottom-up segment tree, we find the node correspondin...
With SR’s minimal source router configuration requirement, its ability to implement policies with specific optimization objectives and constraints and use SR-PCE to dynamically generate optimal multicast trees (including when topology changes occur in t...
Database query optimization Notes: The Bloom Filter automatically optimizes the number of hash functions and bit array size based on the expected number of items and desired false positive rate. The actual false positive rate may vary slightly from the target rate due to the probabilistic nature ...
另外要记住的是打开optimization.usedExports。在mode: "production"模式下,它也是默认打开了的。它告诉webpack每个模块明确使用exports。这样之后,webpack会在打包文件中添加诸如/* unused harmony export */这样的注释,其后UglifyJsPlugin插件会对这些注释作出理解。
optimization: { minimize: true, usedExports: true, }, }; 这样编译后就将没有用到的变量 username 和 foo 函数都移除掉了 sideEffects 这时候仍存在一个问题,如果通过模块化引入另一个js文件,即使没有被使用,useExports也不会进行tree shaking。
WTA strategy is used in cost optimization and a weighted median filter is used in the final stage of the stereo matching process. The experimental results show that the combination of CT and ST is working effectively in terms of the absolute error and is comparable to the combination of CT ...
