The MultilevelCropAndResize
plugin performs the ROIAlign operation on the output feature maps from FPN (Feature Pyramid Network). It is used for MaskRCNN inference in Transfer Learning Toolkit.
This plugin supports the NCHW format. It takes multiple inputs: roi
, feature_maps
from FPN.
roi
is the ROI candidates from the MultilevelProposeROI
plugin. Its shape is [N, rois, 4]
where N
is the batch_size, rois
is the number of ROI candidates and 4
is the number of coordinates.
feature_maps
are the output of FPN. In TLT MaskRCNN, the model we provide contains 5 feature maps from FPN's different stages.
This plugin generate one output tensor of shape [N, rois, C, pooled_size, pooled_size]
where C
is the channel of mutiple feature maps from FPN and pooled_size
is the height(and width) of the feature area after ROIAlign.
This plugin has the plugin creator class MultilevelCropAndResizePluginCreator
and the plugin class MultilevelCropAndResize
.
The following parameters were used to create MultilevelCropAndResize
instance:
Type | Parameter | Description |
---|---|---|
int | pooled_size | The spatial size of a feature area after ROIAlgin will be [pooled_size, pooled_size] |
