Visual AI
CycleGAN Unpaired Translation
CycleGAN learns to translate images between two visual domains (like horses to zebras, or photos to paintings) without ever needing matched before-and-after…
Visual AISPADE Semantic Image Synthesis
SPADE (Spatially-Adaptive Normalization) turns a simple labeled layout, like a child's coloring-book map of 'sky here, grass there, tree here'…
Visual AIDragGAN Interactive Editing
DragGAN lets you edit an image by literally dragging points: grab a spot and drag it to a target, and the picture deforms realistically, changing pose…
Visual AIDiffusion Transformers
Diffusion Transformers (DiTs) swap the convolutional U-Net at the heart of image and video generators for a Transformer backbone.
Visual AIFeature Pyramid Networks
Feature Pyramid Networks (FPN) let detectors spot objects at wildly different sizes by building a multi-scale 'pyramid' of features cheaply.
Visual AINon-Maximum Suppression
Non-Maximum Suppression (NMS) is the cleanup step that turns a messy pile of overlapping detection boxes into one tidy box per object.
Visual AISpatial Transformer Networks
Spatial Transformer Networks (STNs) are learnable modules that let a neural network actively warp, rotate, crop, or rescale its input to focus on what…
Visual AIStereo Depth Estimation
Stereo depth estimation recovers how far away things are by comparing two slightly offset camera views, just like your two eyes do.
Visual AIPoint Cloud Processing
A point cloud is a set of 3D points (X, Y, Z) that captures the shape of real objects and spaces, often from LiDAR or depth sensors.
Visual AISigned Distance Functions
A signed distance function (SDF) describes a 3D shape by telling you, for any point in space, how far it is to the nearest surface, with a sign that says…
Visual AIDeformable Convolutions
Deformable convolutions let a neural network bend its sampling grid to follow the actual shape of objects instead of forcing it through a rigid square window.
Visual AIDINO Self-Distillation
DINO is a self-supervised method that trains a vision transformer to understand images with no labels at all, by having the network teach itself.
