Pipeline construction for the automated text retrieval, editing, and deletion in comic illustrations
No full textWith the increasing demand for high- quality data in the field of Machine Learning and AI, the availability of such data has become a major bottleneck for further advancements. This paper proposes a novel approach to extract valuable data from comic illustrations, aiming to address the scarcity of labeled datasets. By leveraging popular comic series such as Dilbert, which contain thousands of comic strips with multiple panels, text boxes, characters, and settings, we aim to create a pipeline for data labeling and manipulation. This pipeline will enable experiments in various areas, including generative comics, humor detection, translation, and more. The paper focuses on two key research questions: 1) How accurately can we get current OCR models to extract text from the comics, and 2) How can we create the ability to edit and delete existing text boxes. By accurately segmenting the panels and text boxes within the comics, we expect to improve OCR performance by reducing noise and addressing unique text formats. Object detection models will be employed to zoom into text boxes, further enhancing OCR text extraction accuracy. Evaluation metrics such as Latent Dirichlet allocation (LDA), Character Error Rate (CER), and Word Error Rate (WER) will be used to measure the effectiveness of the proposed techniques. In the end, utilizing a dataset of 500 labelled comic panels, we achieve accuracies of 94.07% for CER (up 9.86% from 84.21% baseline), 88.35% for WER (up 8.35% from 80.0% baseline), and 98.0% for LDA (up 3.77% from 94.23% baseline). Similarly, editing and deleting of text boxes inside the comic panels prove to be successful in a vast majority of instances. We believe these results are more than adequate for select use cases.CSE3000 Research ProjectComputer Science and Engineerin

Push Back The Boundaries: The potential of multimodal concessions to make the modal boundaries in public transport disappear
No full textThe introduction and obligation of tendering PT (concessions) in Europe has led to more focus on cost-efficiency and contracts. An additional effect in regional PT is the increase of undesirable boundaries between train and bus, e.g. in the form of non-aligned tariffs and bad interchange possibilities. The goal of a multimodal concession is to abolish these boundaries and establish an integrated PT system by tendering regional train and bus simultaneously. When the organisational part of integration is established this way, it becomes possible establish operational integration, which is defined as the alignment of the networks, schedules, information, tickets & tariffs, and Traffic Control of regional train and bus. Our analysis shows that internal coordination (in a multimodal concession), set against cases where integration is arranged by a contract or a partnership, indeed leads to more focus and better tuning of most of the five levels. In a particular case, on balance passengers are offered a better aligned PT system and the operator can operate more efficiently. However, not in each case a multimodal concession is most suitable and the risks for operators are large. Besides that, the implementation often is a difficult process. It is concluded that in cases it is possible to tender a multimodal concession, the pros often outweigh the cons.Transport, Infrastructure and Logistic
Lightweight sodium alanate thin films grown by reactive sputtering
No full textWe report the preparation of sodium alanate, a promising hydrogen storage material, in a thin film form using cosputtering in a reactive atmosphere of atomic hydrogen. We study the phase formation and distribution, and the hydrogen desorption, with a combination of optical and infrared transmission spectroscopy. We show that the hydrogen desorption, the phase segregation, and the role of the dopants in these complex metal hydrides can be monitored with optical measurements. This result shows that a thin film approach can be used for a model study of technologically relevant lightweight metal hydrides.DelftChemTechApplied Science
