Bilinear models of natural images

Human Vision and Electronic Imaging XII
Preserved Fulltext
In this paper, we describe how bilinear image models can be used to learn independent representations of the invariances, and their transformations, in natural image sequences. ...
These models provide the foundation for learning higher-order feature representations that could serve as models of higher stages of processing in the cortex, in addition to having practical merit for ...

We show that from an arbitrary set of natural images, the algorithm produces oriented basis filters that can simultaneously represent features in an image and their transformations. ...
We describe an unsupervised algorithm for learning both localized features and their transformations directly from images using a sparse bilinear generative model. ...

However, the hues of adjacent pixels change abruptly by the bilinear interpolation, therefore, we use smooth hue transition interpolation to enhance the edge of original image, and finally we identify ...
The results show that the GB model is right for interpolation algorithm, the others are not correct, because they can not restore the natural colour of the key. ...

Representing images as matrices further lessen the number of parameters to be estimated to define a bilinear projection which maps the image sample to a lowerdimensional bilinear subspace. ...
In this paper, we propose an analytic formulation for low-dimensional subspace construction in which shading cues lie while preserving the natural structure of an image sample. ...
This highlights the benefit of the proposed bilinear appearance model in terms of robustness against noise. ...

More specifically, we find the trained neural network classifier can be fooled by inconsistent implementations of image decoding and resize. ...
These noises are model-agnostic and may cause perceptible perturbation. Natural noises such as Snow noise and Frost noise can measure the robustness of a model in the wild. ...
To solve this problem, a natural way is to make the model "see" all kinds of decoders and resize methods during the training process. ...
