LANDMARK DETECTION WITH AN ITERATIVE NEURAL NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18243555 titled 'LANDMARK DETECTION WITH AN ITERATIVE NEURAL NETWORK
Simplified Explanation
Landmark detection refers to the detection of landmarks within an image or a video, and is used in many computer vision tasks such emotion recognition, face identity verification, hand tracking, gesture recognition, and eye gaze tracking. Current landmark detection methods rely on a cascaded computation through cascaded networks or an ensemble of multiple models, which starts with an initial guess of the landmarks and iteratively produces corrected landmarks which match the input more finely. However, the iterations required by current methods typically increase the training memory cost linearly, and do not have an obvious stopping criteria. Moreover, these methods tend to exhibit jitter in landmark detection results for video. The present disclosure improves current landmark detection methods by providing landmark detection using an iterative neural network. Furthermore, when detecting landmarks in video, the present disclosure provides for a reduction in jitter due to reuse of previous hidden states from previous frames.
- The innovation in this patent application is the use of an iterative neural network for landmark detection, which improves upon current methods that rely on cascaded networks or ensemble models.
- The technology reduces jitter in landmark detection results for video by reusing previous hidden states from previous frames, leading to more stable and accurate landmark tracking.
Potential Applications
The technology can be applied in various fields such as:
- Emotion recognition
- Face identity verification
- Hand tracking
- Gesture recognition
- Eye gaze tracking
Problems Solved
The technology addresses the following issues:
- Linear increase in training memory cost with current landmark detection methods
- Lack of an obvious stopping criteria in current methods
- Jitter in landmark detection results for video
Benefits
The benefits of this technology include:
- Improved accuracy in landmark detection
- Reduction in jitter for video applications
- More efficient memory usage during training
Potential Commercial Applications
The technology can be commercially applied in industries such as:
- Healthcare for patient monitoring
- Security for facial recognition systems
- Entertainment for gesture-based interfaces
Possible Prior Art
One possible prior art for landmark detection in computer vision is the use of deep learning models for facial landmark detection, which have been widely studied in recent years.
