基于堆的优先队列C语言实现

The inverse of the gradient function. I ve provided versions that work on 1-d vectors, or 2-d or 3-d arrays. In the 1-d case I offer 5 different methods, from cumtrapz, and an integrated cubic spline, plus several finite difference methods. In higher dimensions, only a finite difference/linear algebra solution is provided, but it is fully vectorized and fully sparse in its approach. In 2-d and 3-d, if the gradients are inconsistent, then a least squares solution is generated

为改进角点检测算子的检测性能，提高基于角点的图像配准算法的配准精度，把多分辨分析的思想引入到经典 的Harris角点检测中。构造了基于小波变换的灰度强度变化公式，并得到了具有尺度变换特性的自相关矩阵，从而构建 了一种新的Harris多尺度角点检测算法。这样，使得新的角点检测可以在不同的尺度下获取角点，并克服了单一尺度的 Harris角点检测可能存在的角点信息丢失、位置偏移和易受噪而提取出伪角点等问题。然后根据角度直方图得到的旋转 角度，和提取的以角点为中心的特征子图，定义了角点点对的对齐度。最后，运用最大化对齐度准则来精确地确定角点匹 配点对。实验表明，该配准算法具有精确性、有效性和抗噪性，实现了良好的配准效果。
