squeezenet1.0

Use Case and High-Level Description

The squeezenet1.0 model is one of the SqueezeNet topology models, is designed to perform image classification. The SqueezeNet models have been pre-trained on the ImageNet image database. For details about this family of models, check out the repository.

The model input is a blob that consists of a single image of 1, 3, 227, 227 in BGR order. The BGR mean values need to be subtracted as follows: [104, 117, 123] before passing the image blob into the network.

The model output for squeezenet1.0 is the typical object classifier output for the 1000 different classifications matching those in the ImageNet database.
