Anomaly detectors are widely used in industrial manufacturing to detect and localize unknown defects in query images. These detectors are trained on anomaly-free samples and have successfully distinguished anomalies from most normal samples. However, hard-normal examples are scattered and far apart from most normal samples, and thus they are often mistaken for anomalies by existing methods. To address

This position paper argues for the use of structured generative models (SGMs) for the understanding of static scenes. This requires the reconstruction of a 3D scene from an input image (or a set of multi-view images), whereby the contents of the image(s) are causally explained in terms of models of instantiated objects, each with their own type, shape, appearance and pose, along with global variables

Recent advancements in diffusion models have showcased their impressive capacity to generate visually striking images. However, ensuring a close match between the generated image and the given prompt remains a persistent challenge.

End-to-end (E2E) training has become the de-facto standard for training modern deep networks, e.g., ConvNets and vision Transformers (ViTs). Typically, a global error signal is generated at the end of a model and back-propagated layer-by-layer to update the parameters. This paper shows that the reliance on back-propagating global errors may not be necessary for deep learning. More precisely, deep networks

Video synopsis is a technique that condenses a long surveillance video to a short summary. It faces challenges to process objects originally occluding each other in the source video. Previous approaches either treat occlusion objects as a single object, which however reduce compression ratio; or have to separate occlusion objects individually, but destroy interactions between them and yield visual

Zero-cost proxies are nowadays frequently studied and used to search for neural architectures.

Object pose estimation based on a single RGB image has wide application potential but is difficult to achieve. Existing pose estimation involves various inference pipelines. One popular pipeline is to first use Convolutional Neural Networks (CNN) to predict 2D projections of 3D keypoints in a single RGB image and then calculate the 6D pose via a Perspective-n-Point (PnP) solver. Due to the gap between

We suppose this is because of the absence of explicit supervision and the inherent gap between real-world low-light domain and the training low-light domain. For example, low-light datasets are well-designed, but real-world night scenes are plagued with sophisticated

While individual LBP-based methods yield good results, co-occurrence LBP-based methods exhibit a better ability to extract structural information. However, most of the co-occurrence LBP-based methods excel mainly in dealing with rotated images, exhibiting limitations

StyleGAN models show editing capabilities via their semantically interpretable latent organizations which require successful GAN inversion methods to edit real images. Many works have been proposed for inverting images into StyleGAN’s latent space. However, their results either suffer from low fidelity to the input image or poor editing qualities, especially for edits that require large transformations
