A Large-scale High-diversity Benchmark for RGBT Tracking
LasHeR: A Large-scale High-diversity Benchmark for RGBT Tracking
Motivation
RGBT tracking receives a surge of interest in the computer vision community, but this research field lacks a large-scale and high diversity benchmark dataset, which is essential for both the training of deep RGBT trackers and the comprehensive evaluation of RGBT tracking methods. To this end, we present a Large-scale High-diversity benchmark for RGBT tracking (LasHeR) in this work.
About LasHeR benchmark
- Large-scale
- Multi-platform imaging devices
- Rich scenes and categories
- Real-world challenges
LasHeR consists of 1224 visible and thermal infrared video pairs with more than 730K frame pairs in total. Each frame pair is spatially aligned and manually annotated with a bounding box, making the dataset well and densely annotated. LasHeR is highly diverse capturing from a broad range of object categories, camera viewpoints, scene complexities and environmental factors across seasons, weathers, day and night. Induced by real-world applications, several new challenges are take into consideration in data creation.
Comparison of LasHeR with public RGBT datasets
Attributes
| Attr | Description |
|---|---|
| NO | No Occlusion - the target is not occluded. |
| PO | Partial Occlusion - the target object is partially occluded. |
| TO | Total Occlusion - the target object is totally occluded. |
| HO | Hyaline Occlusion - the target is occluded by hyaline object. |
| OV | Out-of-View - the target leaves the camera field of view. |
| LI | Low Illumination - the illumination in the target region is low. |
| HI | High Illumination - the illumination in the target is too strong to identify the target. |
| AIV | Abrupt Illumination Variation - the illumination of the target changes significantly. |
| LR | Low Resolution - the resolution in the target region is low. |
| DEF | Deformation - non-rigid object deformation. |
| BC | Background Clutter - the background information which includes the target object is messy. |
| SA | Similar Appearance - there are objects of similar shape near the target. |
| TC | Thermal Crossover - the target has similar temperature with other objects or background surroundings. |
| MB | Motion Blur - the target object motion results in the blur image information. |
| CM | Camera Moving - the target object is captured by moving camera. |
| FL | Frame Lost - some of thermal or visible frames are lost. |
| FM | Fast Motion - the motion of the ground truth between two adjacent frames is larger than 20 pixels. |
| SV | Scale Variation - the ratio of the first bounding box and the current bounding box is out of the range [0.5,2]. |
| ARC | Aspect Ratio Change - the ratio of bounding box aspect is outside the range [0.5,2]. |

Evaluation on LasHeR
We evaluate 12 RGBT tracking algorithms on the entire LasHeR to provide comprehensive platform of performance analysis. Deep RGBT trackers include MANet, DAPNet, MaCNet, DAFNet, FANet, MANet++, DMCNet and mfDiMP. RGBT trackers based on handcrafted features include SGT, CMR and SGT++.
Retraining experiment on LasHeR
we split LasHeR into training and testing subsets according to the target class distribution. And we conduct the retraining experiment by retraining MANet and mfDiMP on training set to demonstrate how deep RGBT trackers can be improved using a large-scale training set.
