weak image

The segmentation experiment on each types of cervical cell image shows that by means of adjustment of weight values of two level set functions, any cell image with weak edges can be segmented precisely.

对各类宫颈细胞图像的分割实验表明，通过调整两个独立水平集的加权系数就能够实现任意弱边界细胞图像组成区域的分割。

Using this method a human palm ultra weak luminescence photon image is processed.

并用此方法处理了人手掌的超微弱发光光子图像.

Generally, due to the lower spatial resolution of hyperspectral image, and the effect of the target size and complex features, make the interested target in hyperspectral images often in a state of subpixel or weak information.

通常，由于高光谱图像较低的空间分辨率以及受到目标尺寸和地物复杂特性的影响，使得感兴趣目标在高光谱图像中往往处于亚像元级或弱信息状态。

Because the urine image is a kind of typical weak-edge image, the classical methods to detect the edge can't work excellently. In this paper, a modified Snake algorithm is proposed.

由于尿液图像是典型的弱边缘图像，经典的边缘提取方法均不能取得良好的效果，在此介绍了一种改进型Snake算法。
