“In addition, the int type, while normally considered signed, was treated as an unsigned number by bitwise andshift operationsand by conversions to/from octal and hexadecimal representations. Longs, on the other hand, were always considered signed. Therefore,some operations would produce a different...

A logical right shift, also known as an unsigned right shift or a zero-fill right shift, moves the entire binary sequence, including the sign bit, and fills the resulting gap on the left with zeros:Notice how the information about the sign of the number is lost. Regardless of the ...
首先,我们将使用一组库来进行经典的图像处理:从提取图像数据开始,使用一些算法转换数据,使用库函数进行预处理、增强、恢复、表示(使用描述符)、分割、分类、检测和识别(对象)以进行分析、理解,并更好地解释数据。接下来,我们将使用另一组库来进行基于深度学习的图像处理,这是一种在过去几年中非常流行的技术。 图像...
