Teaching communication behaviour through dance and movement to children with Autism Spectrum Disorder (ASD) in Sarawak / Teo Jing Xin...[et al.]
This paper highlights the struggles of parents in Sarawak that have children with autism spectrum disorders (ASD), and introduces the authors’ proposed intervention programme for this population. With the belief that parental buy-in to an intervention would result in a higher level of follow-through and therefore improvement to the benefit of their children, the Fun, Inclusive, and Tolerant (FIT) dance and movement based behavioural intervention was designed and developed for Sarawakian children on the spectrum, specifically with the objective to acknowledge and address parental cultural narratives, desires, and expectations; while teaching appropriate behaviours to their children. The focus of this paper is two-fold. Firstly, to demonstrate how dances in this programme were created, by explaining the formulation of an individual dance which was developed for a child with an expressive speech delay; and secondly, to present parental feedback regarding the programme. Concluding remarks touch upon the authors’ future directions in this research
Region-based convolutional neural networks for occluded person re-identification
In a variety of applications, including intelligent surveillance systems, targeted tracking, and assistive human-following robots, the ability to accurately identify individuals even when they are partially obscured is imperative. Such Continuous person tracking is complicated by the close similarity between the appearance of people and target occlusions. This study addresses this significant challenge by proposing a two-step, detection-first approach that uses a region-based convolutional neural network (R-CNN) as the re-identification (re-ID)solution. The model is specifically trained to detect occluded persons at different levels of occlusion before forwarding the image for the re-ID process. Three occluded-specific datasets are selected to evaluate the model's effectiveness in detecting occluded people. There are 379 distinct people in total, and each has five images obstructed from different angles. A sample of the data is taken to simulate various environment settings, and new data points are generated with different degrees of occlusion to assess how well the model performs under varying levels of obstruction. The findings demonstrate that the proposed person re-ID model is reliable in most circumstances, correctly re-identifying at 74% (Rank-1) and 90% (Rank-5). Although there is a decrease in accuracy as the number of distinctive people in the dataset increases, this does not significantly impact the tracking performance in various applications, which are expected to recognize a single person or a small group of individuals. Future works will explore refining similarity matching algorithms by delving into robust image comparison techniques, thereby addressing the challenges presented by occlusions. A critical aspect is to assess the model under diverse lighting conditions and investigate scenarios with multiple individuals in a frame. It is also beneficial to exploit high-resolution datasets, such as DukeMTMC-reID, and integrate finer contextual details, like clothing or carried objects. These collective efforts are essential for optimizing the model’s efficacy in practical applications and advancing person re-ID technologies
Assessing Trustworthy AI in times of COVID-19. Deep Learning for predicting a multi-regional score conveying the degree of lung compromise in COVID-19 patients
Abstract—The paper's main contributions are twofold: to demonstrate how to apply the general European Union’s High-Level Expert Group’s (EU HLEG) guidelines for trustworthy AI in practice for the domain of healthcare; and to investigate the research question of what does “trustworthy AI” mean at the time of the COVID-19 pandemic. To this end, we present the results of a post-hoc self-assessment to evaluate the trustworthiness of an AI system for predicting a multi-regional score conveying the degree of lung compromise in COVID-19 patients, developed and verified by an interdisciplinary team with members from academia, public hospitals, and industry in time of pandemic. The AI system aims to help radiologists to estimate and communicate the severity of damage in a patient’s lung from Chest X-rays. It has been experimentally deployed in the radiology department of the ASST Spedali Civili clinic in Brescia (Italy) since December 2020 during pandemic time. The methodology we have applied for our post-hoc assessment, called Z-Inspection®, uses socio-technical scenarios to identify ethical, technical and domain-specific issues in the use of the AI system in the context of the pandemic.</p
Spatial query retrieval model by single measure similarity (SMSS)
Structural spatial query is an active research area in spatial databases. The assessment of structural spatial query similarity is called structural similarity, also known as configuration similarity. This research developed a structural Spatial Query Retrieval Model for spatial databases by Spiral Web representation. The Spiral Web representation model is able to represent the unique relations among query objects in a structural spatial query like neighborhood relation, relative distance, relative direction and object geometry
Intelligent citrus seed identification
Feature extraction in image processing is a research domain that changes rapidly. [4] introduces a model for identifying seeds from citrus MRI imagery for fruit packaging industry. Hence this research proposed a model for identifying seeds from MRI imagery preprocessed with wavelet transformation and active region identification. The proposed approach segments a citrus imagery into circular layers and wedges to identify the area of interest for seeds. This reduces searching space (in number of pixels) to find out whether a fruit contain seeds. This paper presents the conceptual design and findings from the research on seed identification from citrus imagery segmentation. The improvement might be suitable for bio systems engineering to differentiate fruits with and without seeds
Portable real time needs expression for people with communication disabilities
This paper discusses a research on biometrics information recognition in real time for expressing needs of the people with communication disabilities. They have facial expression ability and incomprehensible speech that can be interpreted to communicate their needs. We utilized the real time detected face features in the pattern recognition process. Their facial expressions for a specific need may not be identical but have some similarities that can be identified through pattern recognition and trained using artificial intelligence. EmoCom has achieved a recognition rate of 85% in both cluttered indoor and outdoor environment
Portable real time emotion detection system for the disabled
This paper discusses the development of a portable real time emotion detection system for the use of disabled. This system allows the user to train the system with his/her profile comprising of expressions shown on the faces when different emotions occur. With a trained profile that can be updated flexibly, a user can detect his/her behaviour on real time basis. It utilizes the state of the art of face detection and recognition algorithms. The combination of Viola-Jones is used to detect frontal face from video which integrates Haar like features, integral image and AdaBoost learning rule. Principal Component Analysis that uses Eigenfaces to detect emotion shown on the faces is applied. For portability, it requires only a laptop or palmtop with built in camera and speaker that can be mounted on wheelchair easily. It works well in both indoor and outdoor environment day and night

Gabor neural network based facial expression recognition for assistive speech expression
This research focuses on utilizing the biometrics recognition to trigger the speech expresser. Our selected biometric is facial expression. Though CPC have no verbal language ability, they have facial expression ability that can be interpreted to relate to their voice speech needs. However facial expression of a CPC may not be exactly identical at all times. Furthermore CPC are unique and require special speech profiles. After a thorough research in face recognition and artificial intelligence domain, neural network coupled with Gabor feature extraction is found to outperform others. A Neural Network with Gabor filters is built to train the facial expression classifiers. This research has proven successful to help CPC to express their voice speech through software with 98% successful facial recognition rate
