Documentation Help Center. Load the 'model. The network can detect objects from 20 different classes [4]. In this example you add an output layer to the imported layers, so you can ignore this warning.

The network in this example contains no unsupported layers. Note that if the network you want to import has unsupported layers, the function imports them as placeholder layers. Before you can use your imported network, you must replace these layers. For more information on replacing placeholder layers, see findPlaceholderLayers Deep Learning Toolbox.

YOLO v2 uses predefined anchor boxes to predict object location. The anchor boxes used in the imported network are defined in the Tiny YOLO v2 network configuration file [5].

The ONNX anchors are defined with respect to the output size of the final convolution layer, which is by To use the anchors with yolov2ObjectDetectorresize the anchor boxes to the network input size, which is by The anchor boxes for yolov2ObjectDetector must be specified in the form [height, width].

For efficient processing, you must reorder the weights and biases of the last convolution layer in the imported network to obtain the activations in the arrangement that yolov2ObjectDetector requires.

However, in the last convolution layer, which is of size by, the activations are arranged differently. Each of the 25 channels in the feature map corresponds to:.

Use the supporting function rearrangeONNXWeightslisted at the end of this example, to reorder the weights and biases of the last convolution layer in the imported network and obtain the activations in the format required by yolov2ObjectDetector. Replace the weights and biases of the last convolution layer in the imported network with the new convolution layer using the reordered weights and biases.

Create both of these layers, stack them in series, and attach the YOLO v2 transform layer to the last convolution layer. The ElementwiseAffineLayer in the imported network duplicates the preprocessing step performed by yolov2ObjectDetector.

Hence, remove the ElementwiseAffineLayer from the imported network. Assemble the layer graph using the assembleNetwork function and create a YOLO v2 object detector using the yolov2ObjectDetector function. Williams, John Winn, and Andrew Zisserman.
