• Abstract: In the dataset of image captioning, each image is aligned with several captions. Despite the fact that the quality of these descriptions varies, existing captioning models treat them equally in the training process. In this paper, we propose a new control signal of sentence quality, which is taken as an additional input to the captioning model. By integrating the control signal information, captioning models are aware of the quality level of the target sentences and handle them differently. Moreover, we propose a novel reinforcement training method specially designed for the control signal of sentence quality: Quality-oriented Self-Annotated Training (Q-SAT). Equipped with R-Drop strategy, models controlled by the highest quality level surpass baseline models a lot on accuracy-based evaluation metrics, which validates the effectiveness of our proposed methods.

  We introduce a method to adapt captioning networks to the semantics of alternative settings, such as capturing audibility in audio captioning. Our framework consists of two main components: (i) a frozen captioning system incorporating a language model (LM), and (ii) a text classifier that guides the captioning system. Notably, when combined with an existing zero-shot audio captioning system, our framework improves its quality and sets state-of-the-art performance in zero-shot audio captioning.

  We propose vision-language consistency guided multi-modal prompt learning for blind image quality assessment (AGIQA) Specifically, we introduce learnable textual and visual prompts in language and vision branches of Contrastive Language-Image Pre-training (CLIP) models. We design a text-to-image alignment quality prediction task, whose learned vision-language consistency knowledge is used to guide the optimization of the above multi-modal prompts.

  A major drawback of state-of-the-art NR-IQA methods is their limited ability to generalize across diverse IQA settings. Recent text-to-image generative models generate meaningful visual concepts with fine details related to text concepts. In this work, we leverage the denoising process of such diffusion models for generalized IQA by understanding the degree of alignment between learnable quality-aware text prompts and images.

  Our framework posits that good image captions should balance three key aspects: informationally sufficient, minimally redundant, and readily comprehensible by humans. We introduce the Pyramid of Captions (PoCa) method, which generates enriched captions by integrating local and global visual information.

• Multi-Modal Prompt Learning on Blind Image Quality Assessment [65.0676908930946]
  Image Quality Assessment (IQA) models benefit significantly from semantic information, which allows them to treat different types of objects distinctly. Traditional methods, hindered by a lack of sufficiently annotated data, have employed the CLIP image-text pretraining model as their backbone to gain semantic awareness. Recent approaches have attempted to address this mismatch using prompt technology, but these solutions have shortcomings. This paper introduces an innovative multi-modal prompt-based methodology for IQA.

  Existing text-to-image diffusion models struggle to synthesize realistic images given dense captions. We propose DenseDiffusion, a training-free method that adapts a pre-trained text-to-image model to handle such dense captions. We achieve similar-quality visual results with models specifically trained with layout conditions.

  We propose a learnable sampling model, Text-Conditioned Token Selection (TCTS), to select optimal tokens via localized supervision with text information. TCTS improves not only the image quality but also the semantic alignment of the generated images with the given texts. We validate the efficacy of TCTS combined with Frequency Adaptive Sampling (FAS) with various generative tasks, demonstrating that it significantly outperforms the baselines in image-text alignment and image quality.

• Macroscopic Control of Text Generation for Image Captioning [4.742874328556818]
  Two novel methods are introduced to solve the problems respectively. For the former problem, we introduce a control signal which can control the macroscopic sentence attributes, such as sentence quality, sentence length, sentence tense and number of nouns etc. For the latter problem, we innovatively propose a strategy that an image-text matching model is trained to measure the quality of sentences generated in both forward and backward directions and finally choose the better one.
