Converts a floating point value to IEEE 754 32 bit binary representation. Sign Bit: 1 Exp: 2 to 9 Frac: 10:32 Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used. For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following: (− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375 ​

提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)
