                Since its inception by **Alan Turing** in 1950, the **Turing Test** has been a fundamental benchmark for 
                evaluating machine intelligence against human standards. As technology evolves, so too must the criteria 
                for assessing AI. The **Visual Turing Test** represents a modern extension that includes visual cognition 
                within the scope of AI evaluation. At the forefront of this advancement is **Visual Question Answering 
                (VQA)**, a field that challenges AI systems to perceive, comprehend, and articulate insights about 
                visual inputs in natural language. This progression reflects the complex interplay between perception 
                and cognition that characterizes human intelligence, positioning VQA as a crucial metric for gauging 
                AI’s ability to emulate human-like understanding.
                
                Mature VQA systems hold transformative potential across various domains. In robotics, VQA systems can 
                enhance autonomous decision-making by enabling robots to interpret and respond to visual cues. In 
                medical imaging and diagnosis, VQA systems can assist healthcare professionals by accurately 
                interpreting complex medical images and providing insightful answers to diagnostic questions, thereby 
                enhancing both the speed and accuracy of medical assessments. In manufacturing, VQA systems can optimize 
                quality control processes by enabling automated systems to identify defects and ensure product 
                consistency with minimal human intervention. These advancements underscore the importance of developing 
                robust VQA capabilities, as they push the boundaries of the Visual Turing Test and bring us closer to 
                achieving true human-like AI cognition.
                
                Unlike other vision-language tasks, VQA requires many CV sub-tasks to be solved in the process, 
                including: **Object recognition**, **Object detection**, **Attribute classification**, **Scene 
                classification**, **Counting**, **Activity recognition**, **Spatial relationships among objects**, 
                and **Commonsense reasoning**. These VQA tasks often do not require external factual knowledge and only 
                in rare cases require common-sense reasoning. Furthermore, VQA models cannot derive additional knowledge 
                from existing VQA datasets should a question require it, therefore **Knowledge-Based Visual Question 
                Answering (KB-VQA)** has been introduced. KB-VQA is a relatively new extension to VQA with datasets 
                representing a knowledge-based VQA task where the visual question cannot be answered without external 
                knowledge, where the essence of this task is centred around knowledge acquisition and integration with 
                the visual contents of the image.

            This application showcases the advanced capabilities of the KB-VQA model, empowering users to seamlessly 
            upload images, pose questions, and obtain  answers derived from both visual and textual data. 
            By leveraging sophisticated Multimodal Learning techniques, this project bridges the gap between visual 
            perception and linguistic interpretation, effectively merging these modalities to provide coherent and 
            contextually relevant responses. This research not only showcases the cutting-edge progress in artificial 
            intelligence but also pushes the boundaries of AI systems towards passing the **Visual Turing Test**, where 
            machines exhibit **human-like** understanding and reasoning in processing and responding to visual 
            information.
