Obj2Seq: Formatting Objects as Sequences with Class Prompt for Visual Tasks

Introduction

This repository is an official implementation of the Obj2Seq.
Obj2Seq takes objects as basic units, and regards most object-level visual tasks as sequence generation problems of objects.
It first recognizes objects of given categories, and then generates a sequence to describe each of these objects. Obj2Seq is able to flexibly determine input categories and the definition of output sequences to satisfy customized requirements, and be easily extended to different visual tasks.

Main Results

All results are trained with a ResNet-50 backbone.

Object Detection

	Epochs	Params(M)	$AP$	Model
DeformableDETR$^\dagger$	50	40	44.6	model
Obj2Seq	50	40	45.7	model
+ iterative box refine	50	42	46.7	model

$^\dagger$ We convert official DeformableDETR checkpoint with this script.

Human Pose Estimation

	Epochs	Params(M)	$AP_{box}$	$AP_{kps}$	Config/Model
Baseline	50	40	55.4	57.9	model
Obj2Seq	50	40	55.4	61.2	model
Obj2Seq	150	40	58.1	65.1	model

You may also download these models from BaiduNetdisk.
