Deep Convolution Neural Network (DCNN) is a popular scene classification method. However
with the neural network deeper and wider
the difficulty of training network also increases. Some scholars have proposed crop images randomly to reduce the difficulty of network training
which will reduce the relevance of the cropped image to the label. To solve this
we propose a scene classification algorithm based on adaptively regional supervision
which is constructed by three parts: heat map generation layer
adaptively supervised cropping layer
and classification layer. The algorithm generates heat map for each image
adaptively crops the image based on the heat map
and finally classifies the cropped images
which improves the relevance of the cropped images to labels. Experiments on the 15-Scene and MIT Indoor datasets show our algorithm outperforms the original network architecture in training efficiency and recognition performance
which shows the accuracy and robustness of our algorithm.
