海洋背景下的海面舰船快速检测算法

摘要

针对海洋背景下海面舰船检测存在的问题，本文提出了一种海洋背景下海面舰船快速检测方法，该方法通过计算图像的高斯金字塔高频分量，得到三层拉普拉斯降维图，第二层降维图与原图相比，维数降低了16倍；对降维图通过改进Sobel检测，增强降维图中舰船目标对比度，突出感兴趣区域，实现快速检测。实验结果表明，该方法具有一定的鲁棒性，能够实现海面舰船的快速检测。%Aiming at the detection of the ship on sea surface under the ocean background,a fast detecting algorithm for ships on sea surface is proposed. The high frequency component of Gaussian pyramid in the image is calculated,and three layer dimension reducing images of Laplacian pyramid are obtained. Compared with the original image,the di-mensionality of the second layer dimension reducing image is reduced by 1 6 times. After that,based on the improved Sobel edge detection in dimension reducing image,the contrast of ships is enhanced and the region of interest is high-lighted to achieve rapid detection. The experiment results show that this method has certain robustness and can a-chieve the fast detection of ships on sea surface.
