【摘要】 提出一种基于FPGA动态可重构的图像融合算法。该方法对小波分解后的图像低频子带采用平均融合算子处理,在高频子带的融合中依据小波系数树状结构特点,提出了一种新的自适应融合方法,最后经过小波逆变换得到融合图像。核心算法集成到一片FPGA中实现,提高算法的实时性,降低系统的实际功耗,有效地减少融合图像的失真。更多还原

【Abstract】 An image fusion algorithm present is presented based on dynamically reconfigurable FPGA.The decomposed low frequency sub-band is fused by mean operator,and the high frequency sub-bands use a new adaptive method which considered the tree characteristic of wavelet coefficients.Finally,the fusion image date is obtained by taking the inverse wavelet transform.Core algorithm integrated into an FPGA implementation,improve real-time algorithm,reducing the actual power consumption,effectively reduce the integration of image distortion.更多还原
