基于Radon变换提出了一种新的图像识别方法，首先构造了二维图像在Radon变换空间的平移和比例 不变量，然后根据变换空间数据的特性，利用奇异值分解得到了旋转不变量并将其用于三类飞机的识别，仿真结果表明该方法具有很好的性能和较高的实用价值。(I nt hisp aper,a n ewi mager ecognitionm ethodb asedo nR adont ransform isp roposed,2一Di magem omentin variant basedo nR adontr ansformi sc onstructed.A ccordingto t hed atain t hetr ansforms pace,Si ngularV alueD ecomposition(SV D)i s proposedh ereto o btainr otationi nvariant.Si mulationr esultsa reg ivent oo btaini nsightin tot hee fficiencieso fferedb yo urm ethod)

采用神经网络实现手写识别的一种方法，建立Bp神经网络，采用快速训练方法，可快速完成一类相关手写字体的模式识别，识别率较高，当字体变化较大识别率降低时，可重新训练具有较强的适应性。实验证实本方法较好实现了手写字符识别，但也存在识别速度较慢，有时训练不收敛等缺点(Handwriting recognition using neural network is a way to establish Bp neural network, using fast training methods, and can be related to the completion of a class of handwriting pattern recognition, recognition rate higher recognition rate when the font changed greatly reduced, they can re- Training has strong adaptability. Experiments confirmed that this method achieved a better handwritten character recognition, but there are also identified slow, and sometimes non-convergence of the training deficiencies)
