BRIEF-based face descriptor: an application to automatic facial expression recognition (AFER)

Nora Al-Garaawi et al.

Summary: This paper introduces a new face descriptor based on BRIEF, which has the characteristics of independence, simplicity in computation, and compact representation, able to generate discriminative features globally and capture local properties when used in regions without explicit shape. Evaluation on three different facial expression databases shows that BRIEF provides satisfactory performance, comparable to alternative face representations in terms of memory usage and execution time.

Two-Stage vSLAM Loop Closure Detection Based on Sequence Node Matching and Semi-Semantic Autoencoder

Zhonghua Wang et al.

Summary: A new two-stage loop closure detection (LCD) strategy is proposed in this paper, incorporating the front-end sequence node level matching (FSNLM) and back-end image level matching (BILM) algorithms. By using a convolutional neural network (CNN) as a feature detector and an improved semantic model DeepLab_AE designed by researchers, accurate local optimal matching nodes are found to achieve scene understanding and place recognition. Experimental results demonstrate that the algorithm outperforms other state-of-the-art algorithms on five public datasets.

Explainable identification and mapping of trees using UAV RGB image and deep learning

Masanori Onishi et al.

Summary: The study developed a machine vision system for tree identification and mapping using RGB images captured by a UAV and CNN. The system successfully classified seven tree classes with over 90% accuracy, and the Guided Grad-CAM analysis showed that the CNN classified trees based on their shapes and leaf contrasts, enhancing the system's potential for cost-effective classification of individual trees with similar colors.

Interactive 3D Graph SLAM for Map Correction

Kenji Koide et al.

Summary: This study introduces an interactive graph SLAM framework with a 3D LIDAR, allowing users to correct 3D environmental maps interactively and achieve globally consistent maps through pose graph optimization and map correction constraints. The proposed semi-automatic loop closing and plane-based map correction techniques, along with a pose constraint update approach, improve mapping consistency and accuracy with minimal human effort, outperforming current automatic SLAM frameworks.

Revisiting Visual-Inertial Structure-From-Motion for Odometry and SLAM Initialization

Georgios Evangelidis et al.

Summary: In this letter, an efficient closed-form solution is proposed for state initialization in visual-inertial odometry (VIO) and simultaneous localization and mapping (SLAM). The direct triangulation of unknown 3D points paired with their observations leads to decreased velocity and point reconstruction error, as well as a more accurate and efficient solution.

Zahra Hossein-Nejad et al.

Summary: The study introduces an adaptive method for eliminating redundant keypoints in SIFT algorithm, improving image matching performance. By analyzing the histogram of keypoints distances, selecting the optimal threshold, and adaptively adjusting the threshold for different images, the method enhances the efficiency of RKEM-SIFT in eliminating redundant keypoints and outperforms SIFT, A(2) SIFT, and RKEM-SIFT in terms of matching performance indices.
