the pareidolia test a simple neuropsychological test measuring Visual Hallucination like illusions
PLOS ONE, 2016Co-Authors: Yasuyuki Mamiya, Yoshiyuki Nishio, Hiroyuki Watanabe, Kayoko Yokoi, Makoto Uchiyama, Toru Baba, Osamu Iizuka, Shigenori KannoAbstract:Background Visual Hallucinations are a core clinical feature of dementia with Lewy bodies (DLB), and this symptom is important in the differential diagnosis and prediction of treatment response. The pareidolia test is a tool that evokes Visual Hallucination-like illusions, and these illusions may be a surrogate marker of Visual Hallucinations in DLB. We created a simplified version of the pareidolia test and examined its validity and reliability to establish the clinical utility of this test.

The pareidolia test is a tool that evokes Visual Hallucination-like illusions, and these illusions may be a surrogate marker of Visual Hallucinations in DLB. We created a simplified version of the pareidolia test and examined its validity and reliability to establish the clinical utility of this test. Methods The pareidolia test was administered to 52 patients with DLB, 52 patients with Alzheimer’s disease (AD) and 20 healthy controls (HCs). We assessed the test-retest/inter-rater reliability using the intra-class correlation coefficient (ICC) and the concurrent validity using the Neuropsychiatric Inventory (NPI) Hallucinations score as a reference. A receiver operating characteristic (ROC) analysis was used to evaluate the sensitivity and specificity of the pareidolia test to differentiate DLB from AD and HCs. Results The pareidolia test required approximately 15 minutes to administer, exhibited good test-retest/inter-rater reliability (ICC of 0.82), and moderately correlated with the NPI Hallucinations score (rs = 0.42). Using an optimal cut-off score set according to the ROC analysis, and the pareidolia test differentiated DLB from AD with a sensitivity of 81% and a specificity of 92%. Conclusions Our study suggests that the simplified version of the pareidolia test is a valid and reliable surrogate marker of Visual Hallucinations in DLB.

deeptio a deep thermal inertial odometry with Visual Hallucination
International Conference on Robotics and Automation, 2020Co-Authors: Muhamad Risqi U Saputra, Niki Trigoni, Pedro P B De Gusmao, Yasin Almalioglu, Stefano Rosa, Changhao Chen, Johan Wahlstrom, Wei Wang, Andrew MarkhamAbstract:Visual odometry shows excellent performance in a wide range of environments. However, in Visually-denied scenarios (e.g. heavy smoke or darkness), pose estimates degrade or even fail. Thermal cameras are commonly used for perception and inspection when the environment has low visibility. However, their use in odometry estimation is hampered by the lack of robust Visual features. In part, this is as a result of the sensor measuring the ambient temperature profile rather than scene appearance and geometry. To overcome this issue, we propose a Deep Neural Network model for thermal-inertial odometry (DeepTIO) by incorporating a Visual Hallucination network to provide the thermal network with complementary information. The Hallucination network is taught to predict fake Visual features from thermal images by using Huber loss. We also employ selective fusion to attentively fuse the features from three different modalities, i.e thermal, Hallucination, and inertial features. Extensive experiments are performed in hand-held and mobile robot data in benign and smoke-filled environments, showing the efficacy of the proposed model.
