对典型复杂背景下10幅1000帧图像的仿真结果表明,当信噪比大于或等于1.5时,可以有效检测出运动点目标。
Finally, some simulation results with 1000 frames from 10 typical images in complex background show that moving point targets with SNR not lower than 1.5 can be detected effectively.
要把淹没在噪声背景中的运动点目标检测出来是一个十分困难的问题。
To detect a moving point target that is submerged in noisy background is a very difficult problem.
由于所有性能优良的运动点目标检测算法的运算量和存贮量都很大,为了减少计算量,通常采用两步法宋检测。
All the excellent detection algorithms of the moving point target have huge calculating quantity and need large storage, so the two steps detection method is used to reduce the calculating quantity.
