Human action recognition (HAR) is a high-level and significant research area
in computer vision due to its ubiquitous applications. The main limitations of
the current HAR models are their complex structures and lengthy training time.
In this paper, we propose a simple yet versatile and effective end-to-end deep
learning architecture, coined as TransNet, for HAR. TransNet decomposes the
complex 3D-CNNs into 2D- and 1D-CNNs, where the 2D- and 1D-CNN components
extract spatial features and temporal patterns in videos, respectively.
Benefiting from its concise architecture, TransNet is ideally compatible with
any pretrained state-of-the-art 2D-CNN models in other fields, being
transferred to serve the HAR task. In other words, it naturally leverages the
power and success of transfer learning for HAR, bringing huge advantages in
terms of efficiency and effectiveness. Extensive experimental results and the
comparison with the state-of-the-art models demonstrate the superior
performance of the proposed TransNet in HAR in terms of flexibility, model
complexity, training speed and classification accuracy.

TransNet: A Transfer Learning-Based Network for Human Action Recognition

Transparent objects present multiple distinct challenges to visual perception
systems. First, their lack of distinguishing visual features makes transparent
objects harder to detect and localize than opaque objects. Even humans find
certain transparent surfaces with little specular reflection or refraction,
like glass doors, difficult to perceive. A second challenge is that depth
sensors typically used for opaque object perception cannot obtain accurate
depth measurements on transparent surfaces due to their unique reflective
properties. Stemming from these challenges, we observe that transparent object
instances within the same category, such as cups, look more similar to each
other than to ordinary opaque objects of that same category. Given this
observation, the present paper explores the possibility of category-level
transparent object pose estimation rather than instance-level pose estimation.
We propose \textit{\textbf{TransNet}}, a two-stage pipeline that estimates
category-level transparent object pose using localized depth completion and
surface normal estimation. TransNet is evaluated in terms of pose estimation
accuracy on a large-scale transparent object dataset and compared to a
state-of-the-art category-level pose estimation approach. Results from this
comparison demonstrate that TransNet achieves improved pose estimation accuracy
on transparent objects. Moreover, we use TransNet to build an autonomous
transparent object manipulation system for robotic pick-and-place and pouring
tasks.

TransNet: Transparent Object Manipulation Through Category-Level Pose  Estimation

Transparent objects present multiple distinct challenges to visual perception
systems. First, their lack of distinguishing visual features makes transparent
objects harder to detect and localize than opaque objects. Even humans find
certain transparent surfaces with little specular reflection or refraction,
e.g. glass doors, difficult to perceive. A second challenge is that common
depth sensors typically used for opaque object perception cannot obtain
accurate depth measurements on transparent objects due to their unique

transparent object instances within the same category (e.g. cups) look more
similar to each other than to ordinary opaque objects of that same category.
Given this observation, the present paper sets out to explore the possibility
of category-level transparent object pose estimation rather than instance-level
pose estimation. We propose TransNet, a two-stage pipeline that learns to
estimate category-level transparent object pose using localized depth
completion and surface normal estimation. TransNet is evaluated in terms of
pose estimation accuracy on a recent, large-scale transparent object dataset
and compared to a state-of-the-art category-level pose estimation approach.
Results from this comparison demonstrate that TransNet achieves improved pose
estimation accuracy on transparent objects and key findings from the included
ablation studies suggest future directions for performance improvements.
