low contrast image的意思|示意

In order to solve the problem of detecting moving small targets in low-contrast infrared image sequences, a new detection method based on multilevel filter is proposed.

为了解决低对比度红外序列图像中运动小目标的检测问题，提出了一种基于多级滤波的检测方法。

Experimental results show that the algorithm can enhance the low contrast image effectively and obtain a good visual effect.

实验表明，该算法能有效增强对比度极低的表格图像，使得结果图像有很好的视觉效果。

The main reason is that the resolution and contrast degree of the ultrasonic image itself is very low as well as the influence of intrinsic speckle noises.

其原因主要是超声图像本身分辨率、对比度较低，以及固有的斑点噪声的影响。

Infrared image has the features of high background, low contrast and low SNR.

红外图像具有高背景，低反差，低信噪比等特点。

In the laser video display system, video image with low contrast and inferior image quality are usually happened due to the effects of the background interference fringes.

由于背景干涉条纹的影响，在激光视频显示系统中，通常获得的激光视频图像不仅对比度降低，而且像质较差。
