摘　　要：显微医学图像检索是辅助日常医疗诊断和医学研究的一个重要工具.从显微医学图像具有"分形体"的特点出发,利用基于内积的快速分形编码来提取图像的编码参数及拼贴误差,并将编码参数与拼贴误差相结合,构成改进的联合直方图,图像间的相似性用改进的联合直方图间的距离进行评判.实验结果表明,该算法在基于内容的显微医学图像检索中,具有较好的检索效果.Image retrieval of micro-medicine is an important tool of assisting the daily medical diagnosis and medical research.The micro-medicine images have fractal characteristics,and then using fast fractal image compression algorithm based on inner product extracts the fractal coding parameters and collage errors.The fractal coding parameters and collage errors are combined to form the new joint histogram.It＇s used in calculating the similarity between the two images.Result shows that the fractal joint histogram algorithm is effect in image retrieval of micro-medicine.
