Distinctive contributions of the Magiv3 model  \nWhile the main contribution of this work is the pipeline we propose as a whole, along with the dataset annotations which permit future research and benchmarking, in this section we want to draw attention to the proposed Magiv3 model. Since this model is built on top of Florence-2 [43], we want to be clear and transparent about how our model is distinctive from prior works. Tab. 5 provides an overview.  \n Detection Character Clustering Text-Character Matching OCR Captioning Character Grounding  \nDASS [36] Magiv1 [30]  \nMagiv2 [31] Florence-2 [43] Magiv3 [Ours]  \nCharacters Characters, Texts, Panels  \nCharacters, Texts, Panels, Tails Zero-shot, performs poorly Characters, Texts, Panels, Tails  \nNo  \nYes, using a separate character crop encoder  \nYes, using a separate character crop encoder No  \nYes  \nNo  \nYes  \nYes  \nNo  \nYes  \nNo No, uses a separate model  \nNo, uses a separate model Yes, but line-by-line instead of text-blocks Yes  \nNo  \nNo  \nNo Yes, low quality  \nNo  \nNo  \nNo  \nNo Not really  \nYes  \nTable 5 . Comparison of Magiv3 with prior works.  \nThe notable advantage of Magiv3 is that it is a unified architecture for many manga-related tasks with a single set of model weights. Despite being built on top of Florence-2, Magiv3’s abilities are significantly different. For instance, as shown in Fig. 7, Florence-2 cannot meaningfully ground characters in the given captions. It has no notion of context specific phrase grounding and ultimately finds “class labels” from the captions and predicts boxes for them. Florence-2 also cannot perform character clustering or speaker diarisation which Magiv3 can. Conversely, Magiv3 has not been trained to generate captions due to the high training costs required, while Florence-2 can generate [low quality] captions.  \nAdditionally, Magiv3 can do everything Magiv1, Magiv2 etc. can (and more), without needing a separate crop encoder trained contrastively, or a separate OCR model, or post-processing for ordering. In fact, due to the next token prediction paradigm, we do not have to tweak any thresholds to filter out low confidence predictions; unlike prior works which use finicky hyperparameters which are sensitive to near-boundary predictions. As shown in Fig. 8, the optimal threshold for character detection in Magiv2 tends to either miss predictions or add false positives. In contrast, Magiv3 works much better and hence has a much higher precision for character detection (as noted in the main paper) .  \nThe model is able to handle non-standard grid layouts. For example, in Fig. 8 there is a “non standard” case with a borderless panel and the layout isn’t a typical grid. In general, the model is extremely robust to various panel arrangements. We include a few more examples in Fig. 9.  \nFinally, in terms of generalisation, even though we exclusively train Magiv3 on Japanese comics, it works surprisingly well on Western comics as well. We include examples of this in Fig. 10, where we show predictions on Western comics from the Golden Age of Comic Books, which were not part of the training data. Beyond English texts, Magiv3 can still generalize to a degree–for example, it can successfully predict panels, detect and cluster characters for Chinese/Korean comics etc. However, it has poor text detection and no OCR performance on these langauges as one might expect.  \nB. More on character grounding  \nAs mentioned in Sec. 4.2 of the main paper, here we explore an alternative, training-free, and zero-shot method for obtaining pre-grounded captions for manga panels. In fact this method is leveraged to acquire training data for Magiv3, as alluded to in Sec. 7 of the main paper. Finally, we discuss the inherent limitations of this technique.  \nThe core idea behind this approach is simple yet effective. First, we detect all characters in a manga page using an existing model","cbCaieJ6Dmd1RYfr","https://ap.wps.com/l/cbCaieJ6Dmd1RYfr","pdf",7557605,11,"English","# A.
