A UINT8 is an 8-bit unsigned integer (range: 0 through 255 decimal). Because a UINT8 is unsigned, its first bit (Most Significant Bit (MSB)) is not reserved for signing. This type is declared as follows: typedef unsigned char UINT8; ...
实现对一个8bit位数据(unsigned char类型)的指定位(例如第几位)的置0或者置1操作,并保持其他位不变。 函数原型:void bit_set(unsigned char *data, unsigned char pos, int flag) data是指定的原数据,pos是指定位(取值范围1～8),flag表示置0还是置1操作 //void bit_set(unsigned char *data, unsigned c...
However, to reduce memory requirements for working with images, you can store images as 8-bit or 16-bit unsigned integers using the numeric classes uint8 or uint16, respectively. An image whose data matrix has class uint8 is called an 8-bit image; an image whose data matrix has class ...
int16 — 16-bit signed integer array int32 — 32-bit signed integer array uint32 — 32-bit unsigned integer array int64 — 64-bit signed integer array integer — An array of any of the 8 integer classes above numeric — Integer or floating-point array ...
o 显示器往往只有 8-bit, 而数据有 12- 至 16-bits。 o 如果将数据的 min 和 max 间 (dynamic range) 的之间转换到 8-bit 0-255 去,过程是个有损转换, 而且出来的图像往往突出的是些噪音。 针对这些问题,研究人员先提出一些要求 (requirements),然后根据这些要求提出了一些算法。这些算法现在都很成熟。
Each of the YUV formats described in this article has an assigned FOURCC code. A FOURCC code is a 32-bit unsigned integer that is created by concatenating four ASCII characters. There are various C/C++ macros that make it easier to declare FOURCC values in source code. For example, theMAKE...
Consider that 32-bit floating-point can represent roughly 4 billion numbers in the interval [-3.4e38, 3.40e38]. This interval of representable numbers is also known asthe dynamic-range. The distance between two neighboring representable numbers isthe precision of the representation. ——《Achieving...
首先需要清楚BF16和FP16的区别,网上有图直接拿来用,侵删。首先,我们可以看到,BF16的bit位构成为:符号位1位、指数位8位(和FP32指数位一样)、尾数位7位(小于FP16的10位)。BF16的特点决定了我们不能直接使用FP16的方式进行处理。这是什么意思呢?
