Input images need to have a fixed shape as an input. A CNN is broken down into three different components: the convolutional layers, the pooling layers, and the fully connected layers. 16 seconds per epoch on a GRID K520 GPU. Videos can be understood as a series of individual images; and therefore, many deep learning practitioners would be quick to treat video classification as performing image classification a total of N times, where N is the total number of frames in a video. , classifying short phrases (i. Hopefully, this gives a sense of how to create a CNN for fashion image classification. I know how to get the precision and recall from a custom script.
