Use Case and High-Level Description

The googlenet-v2 model is the second of the Inception family of models designed to perform image classification. Like the other Inception models, the googlenet-v2 model has been pretrained on the ImageNet image database. For details about this family of models, check out the paper.

The model input is a blob that consists of a single image of 1x3x224x224 in BGR order. The BGR mean values need to be subtracted as follows: [104.0,117.0,123.0] before passing the image blob into the network.

The model output for googlenet-v2 is the typical object classifier output for the 1000 different classifications matching those in the ImageNet database.
