Description

NOTE: This plugin is deprecated since TensorRT 9.0. Its functionality has been superseded by the ISliceLayer.

The SpecialSlice plugin slice the detections of MaskRCNN from [y1, x1, y2, x2, class_label, score] to [y1, x1, y2, x2]. It is used in sampleMaskRCNN.

Structure

This plugin supports the NCHW format. It takes one input tensor: detections

detections is the output of DetectionLayer in MaskRCNN model. Its shape is [N, num_det, 6] where N is the batch size, num_det is the number of detections generated from DetectionLayer and 6 means 6 elements of a detection [y1, x1, y2, x2, class_label, score].

This plugin generates one output tensor of shape [N, num_det, 4].

Parameters

This plugin has the plugin creator class FlattenConcatPluginCreator and the plugin class FlattenConcat.

This plugin has no parameter.
