数字水印
- 对原始信号做DCT的算法：Cox 和Piva 等人提出的DCT技术的经典之作。Cox利用随机数发生器产生标准正态序列作为水印信息对图像进行整体DCT变换后，选取除去DC系数之外部分较低频率系数叠加水印信息 Piva则修改整幅图像的中频部分。对原始信号分块后，再作DCT的算法：Hsu和Wu 把图像进行8*8分块，将一个二进制序列作为水印放入DCT的中频区；有些学者则计算整个图像的DCT，把一个实数序列嵌入DCT的中频系数上。选择中频区的好处是一方面尽量减少嵌入信息对图像主观视觉的影响；同时，尽量避
introducesthesingle-chipAT89S52
- 本文介绍了以单片机AT89S52、光电脉宽调制器芯片TL494核心通过用单片机控制调节PWM 的方法，实现单片机控制的DC-DC开关电源电路系统；以及由数模转换芯片ADC0804等构成反馈以得到精确的电压输出的电路系统。由于单片机的电压不稳以及带负载能力不强，所以还包括单片机到DC－DC开关电源之间的稳压以及低通滤波的设计，ADC0804芯片外围电路设计，以及相关的调试与测试方法。-This paper introduces the single-chip AT89S52, photoelect
