Image Recognition and Image Processing Techniques | by ...
Image recognition or a computer vision is a technical discipline that deals with searching the ways to automate all the job that a human visual system can do. ... Independent Component Analysis ...
 Recognizing Facial Actions by Combining Geometric Features ...
Gabor wavelet representation and independent component analysis. All of these systems [1, 7, 11] used a manual step to align the input images with a standard face image using the center of the eyes and mouth. In our previous system [21], multi-state face and facial component models are proposed for tracking and...
Applying Artificial Neural Networks for Face Recognition
The model is assumed to have The strongest edge, correlation, and statistical model of profile. ... The Association of Geometric Feature-Based Method and Independent Component Analysis in Facial Feature Extraction ... “Face recognition by independent component analysis,” IEEE Transactions on Neural Networks, vol. 13, no. 6, pp. 1450–1464 ......
Action recognition based on overcomplete independent ...
Independent component analysis (ICA) , , a specific case of sparse coding when constraining the number of basis functions to equal the feature dimension, also shows similar response properties with simple cells in visual cortex and achieves success in face recognition and action recognition .
3D reconstruction and face recognition using kernel-based ...
Research highlights We propose an improved kernel-independent component analysis method to reconstruct 3D human faces. A three-layer feed-forward neural network trained by a back-propagation algorithm is used to realize a classifier. The experimental results demonstrate that the proposed method is efficient in reconstruction and face recognition applications....
Independent component analysis: an introduction ...
Independent component analysis (ICA) is a method for automatically identifying the underlying factors in a given data set. This rapidly evolving technique is currently finding applications in analysis of biomedical signals (e.g. ERP, EEG, fMRI, optical imaging), and in models of visual receptive fields and separation of speech signals.
Recognizing Action Units for Facial Expression Analysis
optical flow, principal component analysis, independent component analysis, local feature analysis, and Gabor wavelet representation. Best performances were obtained by Gabor wavelet representation and independent component analysis which achieved a 95% average recognition rate for 6 upper face AUs and 6 lower face AUs....
A Robust Method for Nose Detection under Various ...
It depends on the local appearance and shape of nose region characterized by edge information. Independent Components Analysis (ICA) is used to learn the appearance of nose. ... Independent Component Analysis Training Image Independent Component Analysis Edge ... Sejnowski, T.J.: Face recognition by independent component analysis. IEEE Trans ......
Appearance-based three-dimensional object recognition ...
This paper presents results on appearance based 3D object recognition accomplished using Independent Component Analysis (ICA). A database of images captured by a ccd camera was used. The workspace was then sampled in a certain manner.
ICA on Images with Python - Open Source Automation
Also, by its nature, ICA extracts the independent components of images — which means that it will find the curves and edges within an image. For example, in facial recognition, ICA will identify the eyes, the nose, the mouth etc. as independent components. ICA can be implemented in several open source languages, including Python, R, and Scala....
