(Not recommended) DenseNet-201 convolutional neural network

  • DenseNet-201 network architecture

densenet201 is not recommended. Use the imagePretrainedNetwork function instead and specify the "densenet201" model. For more information, see Version History.

Description

DenseNet-201 is a convolutional neural network that is 201 layers deep. You can load a pretrained version of the network trained on more than a million images from the ImageNet database [1]. The pretrained network can classify images into 1000 object categories, such as keyboard, mouse, pencil, and many animals. As a result, the network has learned rich feature representations for a wide range of images. The network has an image input size of 224-by-224. For more pretrained networks in MATLAB®, see Pretrained Deep Neural Networks.

net = densenet201 returns a DenseNet-201 network trained on the ImageNet data set.

This function requires the Deep Learning Toolbox™ Model for DenseNet-201 Network support package. If this support package is not installed, then the function provides a download link.

example

net = densenet201('Weights','imagenet') returns a DenseNet-201 network trained on the ImageNet data set. This syntax is equivalent to net = densenet201.

lgraph = densenet201('Weights','none') returns the untrained DenseNet-201 network architecture. The untrained model does not require the support package.

Examples

Download and install the Deep Learning Toolbox Model for DenseNet-201 Network support package.

Type densenet201 at the command line.

densenet201

If the Deep Learning Toolbox Model for DenseNet-201 Network support package is not installed, then the function provides a link to the required support package in the Add-On Explorer. To install the support package, click the link, and then click Install. Check that the installation is successful by typing densenet201 at the command line. If the required support package is installed, then the function returns a DAGNetwork object.
