A bit shift moves each digit in a number's binary representation left or right. There are three main types of shifts: Left Shifts When shifting left, the most-significant bit is lost, and a 00 bit is inserted on the other end. The left shift operator is usually written as "<<"....
While bit shifting is powerful, it can also be tricky. Shifting negative numbers or using large shift values can lead to unexpected results, especially in languages that handle integer overflow differently. When you use the Bit Shift Calculator, take note of the numerical limits and be careful ...
论文全名:Detecting Text in Natural Image with Connectionist Text Proposal Network 1.摘要 (1)本文提出新型网络CTPN,用于自然图像中的文本行定位。CTPN直接在卷积特征映射中的一系列细粒度文本提议中检测文本行。(创新一)开发了一个垂直锚点机制,联合预测每个固定宽度提议的位置和文本、非文本的分数。(创新二)序列提...
