The invention provides an image classification method based on a low-rank optimization feature dictionary model. The method includes the following image classification steps that firstly, feature points of images are monitored and features of the feature points are described; secondly, a space pyramid ...

An approach to learn a structured low-rank representation for image classification is presented. We use a supervised learning method to construct a discriminative and reconstructive dictionary. By introducing an ideal regularization term, we perform low-rank matrix recovery for contaminated training data ...
Using the tensor network nomenclature, T is a rank two tensor. A tensor’s rank is the number of indices in the tensor—a scalar has rank zero, a vector has rank one, and a matrix has rank two. While the number of dimensions of an array is equivalent to the rank of the tensor, ...
This motivates us to propose a robust domain adaptation image classification method with sparse and low rank representation. Specifically, we first obtain an optimal Domain Adaptation Sparse and Low Rank Representation (DASLRR) for all the data from both domains by incorporating a distribution ...
Section 3 introduces our discriminative dictionary learning with low-rank regularization (D2L2R2) approach. Section 4 presents the optimization algorithm for our model. Section 5 describes the classification scheme. Section 6 shows experimental results on several image datasets. Finally, we draw ...
Image classification scaling performance comparing zero-shot ImageNet top-1 accuracy versus model size. Frozen Encoder Representation One particularly exciting observation is that CoCa achieves results comparable to the best fine-tuned models using only afrozenvisual encoder, in which features extracted aft...
In recent years, more and more deep learning frameworks are being applied to hyperspectral image classification tasks and have achieved great results. However, the existing network models have higher model complexity and require more time consumption. Traditional hyperspectral image classification methods te...
Image segmentation is the process of separating pixels of an image into multiple classes, enabling the analysis of objects in the image. Multilevel thresholding (MTH) is a method used to perform this task, and the problem is to obtain an optimal threshol
