keras 的 example 文件 class_activation_maps.py 解析

该文件功能是实现一个CNN可视化，我不知道这个叫法算不算专业，可以参考别人写的文章

应该就是看下神经网络是通过关注哪部分区域预测出的最终结果

其基础网络是resnet50，get_cam_model函数中对其进行了一点修改，可参考下图，看到修改了哪些地方

就是仅添加了两层神经网络，其他没有动

预测后通过postprocess函数提取出感兴趣的那个分类的channel，我把该函数简化了一下，应该更容易理解一点

def postprocess(preds, cams, top_k=1):
    idxes = np.argsort(preds[0])[-top_k:][0]
    return cams[0, :, :, idxes]

文件最后的代码，我作了如下修改：

# 5. plot image+cam to original size
# plt.imshow(original_img, alpha=0.5)
plt.imshow(cv2.resize(class_activation_map,
                      original_size), cmap='jet')
plt.savefig("res.jpg")
plt.show()

看下效果图

原图

预测后结果的颜色图谱

也就是说，他是根据这部分区域预测出的结果，这是一只金毛犬，下面可以把分类名称打印出来

from keras.applications.imagenet_utils import decode_predictions
print(decode_predictions(preds))

[[('n02099601', 'golden_retriever', 0.82736635), ('n02111129', 'Leonberg', 0.08901908), ('n02111277', 'Newfoundland', 0.008406928), ('n02104029', 'kuvasz', 0.007829149), ('n02099712', 'Labrador_retriever', 0.004909024)]]

如果最后面代码没有修改的话，显示结果为：

就是和原图进行了一个叠加，显示出，哪部分区域，是CNN得出最终预测结果的主要依据

——————————————————

下面是自己折腾时刻，不属于正文

如果我把图片旋转一下，发现resnet几乎无法识别了

[[('n02099601', 'golden_retriever', 0.2694396), ('n02113023', 'Pembroke', 0.16751677), ('n01514859', 'hen', 0.10281576), ('n02105251', 'briard', 0.03323859), ('n02102318', 'cocker_spaniel', 0.03284181)]]

当然，如果水平翻转，还是能识别到的，而且关注点也可以正确的找到

[[('n02099601', 'golden_retriever', 0.82862425), ('n02111129', 'Leonberg', 0.07444748), ('n02104029', 'kuvasz', 0.01596525), ('n02111277', 'Newfoundland', 0.015939327), ('n02099267', 'flat-coated_retriever', 0.0076823044)]]
