- 基于标记的Watershed图像分割算法是一种改进的分水岭算法,它很好地被应用于人脸及其他一些场景图像的分割。把该方法引入高分辨遥感图像的分割,并针对遥感图像的特点,在分割之前采用中值滤波对高分辨率遥感图像进行预处理;同时,在分割过程中采用用小波滤波器替代Butterworth滤波器对梯度图像的低通滤波。不同地物特征Quickbird图像的分割实验表明,对于纹理比较均一的高分辨率遥感图像,该方法避免了过分割现象,且效率较高;但对于纹理比较复杂的图像,该方法具有一定的局限性。-Watershed

- 傅立叶变换在图像处理中的重要作用: (A) 图像增强与图像去噪 绝大部分噪音都是图像的高频分量,通过低通滤波器来滤除高频噪声;边缘也是图像的高频分量,可以通过添加高频分量来增强原始图像的边缘; (B) 图像分割与边缘检测 提取图像高频分量 (C) 图像特征提取 形状特征:傅里叶描述子 纹理特征:直接通过傅里叶系数来计算纹理特征 其他特征:将提取的特征值进行傅里叶变换来使特征具有平移、伸缩、旋转不变性 (D ) 图像压缩 可以直接通过傅里叶系数来压缩数据
