A growth template that can detect the target and noise pixel was put forward.

对现有模板进行改进，提出一种生长模板来对差分图像中的目标点和噪声点进行检测。

This paper mainly investigates the median filtering methods based on the noise pixel detection.

因此，保护细节的中值类滤波算法的研究成为图像去噪领域一个重要的问题。

The second subunit is median filter, which use the median of non-noise pixel in the window to replace the detected noise pixels.

第二部分是中值滤波器，对于检测出的噪声像素，用其相应窗口内的非噪声像素的中值进行替代。

Fujifilm claims they've worked through the pixel noise problems that can accompany massive megapixel sensors (we'll have to see about that), but at the very least the S9000 has a 10.7x optical zoom lens, a 1.8-inch tilting LCD screen, a 0.01 second shutter lag time, dual xD and CompactFlash memory card slots, and can capture RAW images.

The miniaturization of pixel size impacts performance of light sensitivity and signal to noise ratio (SNR) in today's 1.12 micrometer pixel image sensors.

Conventional CMOS image sensors mount the pixel section and analog logic circuit on top of the same chip, which require numerous constraints when wishing to mount the large-scale circuits such as measures to counter the circuit scale and chip size, measures to suppress noise caused by the layout of the pixel and circuit sections, and optimizing the characteristics of pixels and circuit transistors.
