Electrical signals generated in the brain, known as Electroencephalographic signals (EEG) are used to measure electrical activities in the brain. EEG methods being non-invasive, affordable, and portable, are used in this work. analysis of Visual Creativity has clinical application in monitoring the progress of patients suffering from neurodegenerative diseases. In this work, EEG is used to analyze Visual Creativity by classifying the two brain states (1) Creative and (2) Non-creative using the in-house collected data. Data is collected from the participants performing the following tasks: (1) Planning to draw, (2) Drawing, and (3) Monotonous Tasks. Drawing and Monotonous Tasks are considered for the classification in the proposed work. Two types of analysis are carried out (1) converting EEG time-series data into a sequence of topology preserving feature maps and (2) feature maps generated using Spectral Entropy. The EEG data is first pre-processed to down-sample and band-limit the signals followed by ICA to remove the artifact. The artifact-removed EEG data is decomposed into three sub-bands. The decomposed time-series data is converted to a sequence of feature maps that preserves spatial, spectral, and temporal information. Another set of feature maps is also generated using Spectral Entropy from artifact-removed EEG data. Two types of Deep Learning frameworks are proposed (1) VCA-Net video - a deep learning framework consisting of temporal convolution that extracts spatial information and preserves temporal information which is extracted by a combination of LSTM and 1D convolution and (2) VCA-Net image - a deep learning framework which extracts the spatial information using Feature Pyramid Network (FPN) and Atrous Spatial Pyramid Pooling (ASPP). Drawing and Monotonous tasks are classified with a mean accuracy of 70.87% and 65.62% using VCA-Net image and VCA-Net video respectively.

With high maneuverability and strong flexibility, unmanned aerial vehicles (UAVs) have been widely used, especially in the field of transporting payload. However, existing studies mainly study the transportation mode of connecting the payload with a single rope. In order to transport bulky payload while increase the transportation efficiency and guarantee safety, this paper focus on dual-rope tilt-rotor transportation system. The dynamic model is established through Lagrange’s modeling technique and a nonlinear control method is further proposed, which incorporates more swing-related information into the control law. Subsequently, the stability of the closed-loop system is proved by utilizing LaSalle’s invariance principle. Finally, the simulation results are provided.

to improve the clarity of objects in a dark-light environment, and to facilitate the identification and detection of targets behind. People perceive the color and brightness of a point not only depending on the pixel value of the point but also the absolute light entering the human eye is related to the color and brightness around the point. The self-calibration model we used considers the surrounding information, which avoids the information pollution, such as large regions of dark background information. In this model, we introduce a heterogeneous convolution filter, which makes reasonable use of different parts of the filter. Through this operation, information from multiple different scale spaces can be fused, and the field of view when applying the convolution layer is greatly increased without increasing the hyper-parameters, thus producing a more distinctive feature representation. Then the self-calibration model is combined with the backbone reinforcement network, which can not only retain the information of the original scale space but also efficiently collect the latent space information to guide the feature transformation in the original space. After the different channels of the image are processed separately, the dependency between the channels can be established by using the heterogeneous convolution filter. Finally, the test on the ExDark data set proves that our dark target enhancement effect has been significantly improved.

Origami has been applied in robotic design thanks to its lightweight structures and versatile applications. In this paper, we propose and analyze a novel cable-driven Yoshimura continuum actuator. The origami module inspired by the Yoshimura pattern can bend and contract under the actuation of the cable. In addition, we analyze the kinematics of the Yoshimura continuum actuator using the assumption of constant curvature. Based on the kinematic model, a scheme of closed-loop control is designed and validated using the motion capture system. The results show that the kinematic model can predict the tip position of the actuator with the error of 2.14 mm and 3.51mm when following a spiral and a square trajectory. The Yoshimura continuum actuator can track spiral and square trajectories with an error of 1.92 mm and 2.93 mm by the aid of the control method, demonstrating reductions of 10.3% and 16.5% for the average tracking errors. It demonstrates the Yoshimura continuum actuator has the potential to achieve versatile movement.

Mechanical intelligence is the use of mechanical and other physical properties to create robotic systems adaptable to new external situations using simple control schemes. Designs of robot hands have successfully been developed and optimised following this principle to produce self-adaptive and versatile power grasps via implementations based on underactuated fingers, elastic components, and open-loop motor control. However, these characteristics, and mechanical-intelligent strategies in general, have been seldom leveraged for precision grasping. This paper proposes a mechanical-intelligent technique to facilitate not only spiral caging power grasp, but also self-adaptive precision grasp with error tolerance. This approach is exemplified by the rigorous analysis, development, and testing of a novel three-fingered, two-actuator, underactuated robot hand, called the helical hand, which is capable of self-adaptive precision grasping, and of generating spiral helical power grasps of unknown objects by simply setting two actuators at a constant speed.

When taking images against strong light sources, the resulting images often contain heterogeneous flare artifacts. These artifacts can importantly affect image visual quality and downstream computer vision tasks. While collecting real data pairs of flare-corrupted/flare-free images for training flare removal models is challenging, current methods utilize the direct-add approach to synthesize data. However, these methods do not consider automatic exposure and tone mapping in image signal processing pipeline (ISP), leading to the limited generalization capability of deep models training using such data. Besides, existing methods struggle to handle multiple light sources due to the different sizes, shapes and illuminance of various light sources. In this paper, we propose a solution to improve the performance of lens flare removal by revisiting the ISP and remodeling the principle of automatic exposure in the synthesis pipeline and design a more reliable light sources recovery strategy. The new pipeline approaches realistic imaging by discriminating the local and global illumination through convex combination, avoiding global illumination shifting and local over-saturation. Our strategy for recovering multiple light sources convexly averages the input and output of the neural network based on illuminance levels, thereby avoiding the need for a hard threshold in identifying light sources. We also contribute a new flare removal testing dataset containing the flare-corrupted images captured by ten types of consumer electronics. The dataset facilitates the verification of the generalization capability of flare removal methods. Extensive experiments show that our solution can effectively improve the performance of lens flare removal and push the frontier toward more general situations.
