The non-destructive method developed based on hyperspectral imaging (HSI) and electronic nose (E-nose) to rapidly detect microbial content and quality attributes of strawberries during decay, was evaluated. Principal component analysis (PCA) was applied to reduce the dimensionality of the data and to extract featured information from the HSI and E-nose data. Quantitative prediction models were developed...
Key point correspondence plays a critical role in large distance lunar rover localization and navigation, which can decrease accumulative errors and facilitate the rover to approach probing target accurately. Lunar surface images often contain similar patterns, noisy points and obvious illumination changes, especially along with large distance movement, overlapping regions of image pairs have large...
Point matching problem seeks the optimal correspondences between two sets of points. However, the matching result often includes some mismatches that decrease the matching precision. In this paper, we propose a fast algorithm to reject mismatches using pair-wise similarity. The intuition of our algorithm is that the matches should be similar with their neighboring matches due to local consistency...
Key point correspondence plays an important role in lunar surface image processing. Since lunar surface images often contain obvious illumination changes, noisy points and repetitive patterns, traditional appearance based algorithms may fail when local appearance descriptors become less distinctive. In this paper, we introduce a graph matching based algorithm to tackle this problem. First, by incorporating...
Prehensile analysis is a research field attracting multi-disciplinary interests, including computer science, mechanology and neuroscience. For robot, grasp type recognition provides critical information for human-robot interaction and robot self-learning. One of the research direction is to discover the common modes of human hand use with first-person point-of-view wearable cameras. In contrast to...
In industry application, e.g, mineral sorting, various mineral should be picked from the conveyer. The problem can be regarded as grasping prior unknown objects. In this paper, we aim to present a method to grasp the objects with a three-finger gripper guided by vision. Based on our previous works on attractive region, the way to locate a stable grasp is illustrated in the rotation space of the object...
