Chromosome Detection System Using Deep-Learning Technique for Radiation Exposure

Dicentric Chromosome Assay (DCA) has been used for estimating the absorbed radiation dose following occupational or incidental radiation exposure.
The estimating procedure of DCA is labor intensive and time consuming, and therefore, it cannot be widely utilized for radiation mass casualty incidents.
Automatic estimation systems of DCA has been studied to improve the efficiency of the estimation procedure in previous studies. These methods, however, cause significant problems on the accuracy of the chromosome detection.
For improving the accuracy and efficiency of the DCA, an automatic estimation system of DCA using deep learning technique is under development in our research group.

Robust Perception Using Artificial Intelligence

Robots in hazardous robots use optical or acoustic sensors to sense the surrounding environment. In hazardous environment, there is no light source such as the sun and light is severely attenuated and scattered by fog, dust, and water. Therefore, optical sensors have limited views.
On the other hand, acoustic sensors are independent of visibility but have a limitation of low resolution and noise-to-signal ratio.
To recognize the surrounding environment robustly and perform precise mission in harsh condition, various artificial intelligence-based perception algorithms such as target object recognition, image enhancement, and opti-acoustic fusion are required.

3-D Mapping and Localization with limited visibility

In extreme environments with limited visibility, optical sensors have limited performance. The acoustic sensors can be one of the alternatives to the optical sensors in a low-visibility environment. However, the acoustic sensors have poor SNR characteristics, low-resolution problems, and loss of height information.
Therefore, a proper signal processing technique is required. This research is a 3-D seafloor scanning method using multibeam sonar.
It provides a unique analysis of sonar image geometry for extracting missing elevation information and can be continuously executed regardless of the existence of features.
