Pseudo Anomalies Are All You Need: Diffusion-Based Generation for Weakly-Supervised Video Anomaly Detection

WeatherDiffusion has been introduced as a diffusion-based framework that enables controllable weather editing in intrinsic space, utilizing an inverse renderer to estimate material properties and scene geometry from input images. This framework enhances the editing process by generating images based on specific weather conditions described in text prompts.

A novel strategy called Unified Text-Image Embedding (UTIE) has been proposed to mitigate demographic biases in face recognition systems by inducing demographic ambiguity in face embeddings. This approach enriches facial embeddings with information from various demographic groups, promoting fairer verification performance across different demographics.

A novel method for auxiliary diagnosis of Parkinson's disease (PD) has been proposed, utilizing dynamic facial expression analysis to identify hypomimia, a key symptom of the disorder. This approach employs a multimodal facial expression analysis network that integrates visual and textual features while maintaining the temporal dynamics of facial expressions, ultimately processed through an LSTM-based classification network.

A new study introduces a defect-aware hybrid prompt optimization method, termed DAPO, aimed at enhancing zero-shot multi-type anomaly detection and segmentation. This approach leverages high-level semantic information from vision-language models like CLIP, addressing the challenge of recognizing fine-grained anomaly types such as 'hole', 'cut', and 'scratch'.

The Dynamic Image Prompt Adapter (DynaIP) has been introduced as a novel tool aimed at enhancing Personalized Text-to-Image (PT2I) generation, addressing key challenges such as maintaining concept fidelity and scalability for multi-subject personalization. This advancement allows for zero-shot PT2I without the need for test-time fine-tuning, leveraging multimodal diffusion transformers (MM-DiT) to improve image generation quality.

The study introduces a framework that utilizes empty prompts to mitigate template-sample similarity bias in the CLIP model, enhancing its few-shot learning capabilities. This approach reveals and reduces bias during pre-training and enforces correct alignment during fine-tuning, ultimately improving classification accuracy and robustness.

The Large Shapes and Textures dataset (LAS&T) has been introduced to enhance the capabilities of Large Vision-Language Models (LVLMs) in recognizing and representing shapes and textures across various contexts. This dataset, created through unsupervised extraction from natural images, serves as a benchmark for evaluating the performance of leading models like CLIP and DINO in shape recognition tasks.

OpenMonoGS-SLAM has been introduced as a pioneering monocular SLAM framework that integrates 3D Gaussian Splatting with open-set semantic understanding, enhancing the capabilities of simultaneous localization and mapping in robotics and autonomous systems. This development leverages advanced Visual Foundation Models to improve tracking and mapping accuracy in diverse environments.
