【摘要】：针对激光束干扰情况下,高光谱图像存储过程中存在的丢帧问题,提出基于稀疏表示与队列式缓存相结构相结合的高光谱图像数据存储方法研究。首先利用Gabor滤波器组,滤除激光束对高光谱图像的干扰,提高光谱图像的可识别度;基于稀疏表示原理构造训练样本集合,利用获取的基函数字典对高光谱图像数据进行稀疏编码,完成对图像的压缩处理;最后基于队列式缓存结构消除存储速度波动带来的不良影响,实现高光谱图像数据的实时存储。实验证明了提出高光谱图像数据存储方法,能够有效提高存储速度,并解决了图像存储过程中的数据丢失问题。
[Abstract]:Aiming at the problem of losing frames in hyperspectral image storage under laser beam interference, a method of hyperspectral image data storage based on sparse representation and queue buffer structure is proposed. Firstly, the Gabor filter bank is used to store hyperspectral image data. Filter out the interference of laser beam to hyperspectral image, improve the recognition degree of spectral image, construct the training sample set based on sparse representation principle, and use the obtained basis function dictionary to encode the hyperspectral image data sparsely. Finally, based on the queue buffer structure, the bad effect of storage speed fluctuation is eliminated, and the real-time storage of hyperspectral image data is realized. The experimental results show that the hyperspectral image data storage method is proposed. It can effectively improve the storage speed and solve the problem of data loss in image storage process.
