target image area的意思|示意

This paper studies the technology of the wide-area scene mosaics and the target extraction based on the video image sequences.

本文研究了基于视频图像序列的广域场景自动拼接技术，以及视频图像序列目标提取技术。

Area target usually covers a large area and it takes a long mission-complete time for a satellite to cover it completely, which makes the image request difficult to satisfy in a reasonable time.

区域目标相对星载遥感器的视场较大，需卫星多次观测才能完全覆盖，难以在较短的时间内获取其完整的遥感数据。

The image of point target in the imaging area is only several or dozens of pixels. And its strength is relatively weak and drowned in the noise, no obvious size, shape, texture, and other information.

点目标的成像面积仅为几个或几十个象素，目标强度相对较弱，无明显的尺寸、形状、纹理信息可供后续处理系统进行分析使用。

The foreground extraction method is quite suitable for picking up the target contour of the background image in a fixed area, such as monitoring of the surrounding environment of an ATM and the like.

本发明非常适合于固定区域的背景图像中提取目标轮廓，如ATM机周边环境的监控等。

The infrared image includes several aspects: great-area continuous background, small infrared target, noise and so on.

红外图像中包含了大面积连续的背景、红外小目标以及噪声等几个部分。

Finally, make statistics to segmented image and count number and area of the ore target.

最后对分割后的图像进行统计，统计矿石目标个数和面积。
