全色图像的特征均衡增强系统设计

Design of feature equalization enhancement system of panchromatic image

针对传统全色图像的特征均衡增强系统一直存在增强处理效果差的问题,提出一种新的全色图像特征均衡增强系统设计方法。该方法首先对全色图像特征均衡增强系统进行硬件平台设计,硬件平台由串行接口、控制接口和以太网接口构建,利用SURF算法对全色图像进行特征提取,采用不同尺度的滤波器和图像卷积得出全色图像的尺度空间,构建全色图像的尺度空间检测图像特征点对其进行直方图均衡化处理,结合直方图均衡化的整体性和细节性优点,使均衡化后的直方图间实现均匀分布,从而完成对全色图像特征均衡增强系统设计。实验结果证明,利用直方图均衡方法能有效地增强全色图像特征均衡的效果,所设计的系统具有很高的应用性,为该领域的研究发展奠定了坚实基础。

Since the traditional feature equalization enhancement system of the panchromatic image has poor performance of enhancement processing effect,a new design method of the feature equalization enhancement system of panchromatic image is proposed.The hardware platform of the proposed system is designed,which is constructed with serial interface,control interface and Ethernet interface.The SURF algorithm is used to extract the feature of the panchromatic image.The filter and image convolution with different scales are adopted to get the scale space of the panchromatic image.The scale space of the panchromatic image is constructed to detect the image feature point.The panchromatic image is performed with the histogram equalization processing.In combination with the integrity and detail advantages of the histogram equalization,the equalized histogram can realize the uniform distribution,and accomplish the design of the feature equalization enhancement system of the panchromatic image.The experimental results show that the histogram equalization method can improve the feature equilibrium effect of the panchromatic image effectively,the designed system has high applicability and provides a solid foundation for the research and development in this field.
