【摘要】 目标与背景的对比度在目标识别中有着决定性的作用。因此,研究目标相对背景的对比度的测量方法就有着非常重要的意义。本文利用CCD相机获取目标和背景的数字图像,并由此测量对比度。通过使用MATLAB软件对CCD的光谱响应曲线进行拟合,从而对测量数据进行校正,最后得出此方法可行性的结论。更多还原

【Abstract】 The target to background contrast plays key role in object recognition.Therefore it is worth while to do research work in finding out the brightness difference between the target and background.In this paper,CCD camera is used to ac-quire digital images which are used to calculate the contrast.Combining with CCD spectral response curve,the measured data are fitted and corrected on MATLAB platform.The method is proofed practical.更多还原
