The cmap2gray function converts RGB values to grayscale values by forming a weighted sum of the R, G, and B components: 0.298936021293775 * R + 0.587043074451121 * G + 0.114020904255103 * B The coefficients used to calculate grayscale values in the cmap2gray function are identical to those...
3、BP神经网络实现对图像的分类 使用pytorch框架构建神经网络,并进行训练分类,步骤如下: 1、重写Getloader类,使用Dataloader迭代器处理训练数据和测试数据,构建用于模型训练和测试的数据结构,便于后期的使用和扩展。 2、构建一个k×200×350×500×625的神经网络。(k为将为后的图片的特征数,即输入神经元的个数,200、...
