基于OpenCV和OpenMP的多核处理图像边缘检测算法——Sobel的实现。

没有可视化界面。

需要先配置OpenCV和OpenMP。

理论依据：利用OpenMP我们可以实现多核并行处理边缘检测。根据Sobel原理，可以完全明确的是：每一个像素点的梯度计算都不依赖于其他的像素点！这就是实现多核并行处理边缘检测的关键。利用这个关键的特性，我们可以让多个核同时去计算多个像素点的梯度值，进而提高Sobel边缘检测算法的性能。

-The implementation of OpenCV and OpenMP multi-core processing image edge detection algorithm based on Sobel.

No visual interface.

Need to configure OpenCV and OpenMP.

The theory basis: the use of OpenMP we can realize multi core parallel processing edge detection. According to the Sobel principle, can completely clear is the calculation of the gradient of each pixel are not dependent on other pixels! This is the realization of multi core parallel key processing edge detection. Use this key feature, gradient we can allow multiple cores at the same time to compute a plurality of pixel values, and improve the properties of Sobel edge detection algorithm.
