Sketchformer: Transformer-Based Representation for Sketched Structure

CVPR 2020poster

Sketchformer is a novel transformer-based representation for encoding free-hand sketches input in a vector form, i.e. as a sequence of strokes. Sketchformer effectively addresses multiple tasks: sketch classification, sketch based image retrieval (SBIR), and the reconstruction and interpolation of s…

Optical-flow features empirical mode decomposition for motion anomaly detection

ICASSP 2017accepted

In video data analysis of dynamic scenes, temporal characteristics of moving objects play an important role in decision-making. However, the temporal consistency of typical features used for video interpretation is low due to the overlap of the spectra of informative video signal component and the s…

Color description of low resolution images using fast bitwise quantization and border-interior classification

ICASSP 2015accepted

Image classification often require preprocessing and feature extraction steps that are directly related to the accuracy and speed of the whole task. In this paper we investigate color features extracted from low resolution images, assessing the influence of the resolution settings on the final class…
