چکیده
Unsupervised pixel-level defective region segmentation is an important task in image-based anomaly detection for various industrial applications. The state-of-the-art methods have their own advantages and limitations: matrix-decomposition-based are robust to noise, but lack complex background image modeling capability; representation-based good at localization, accuracy shape contour extraction; reconstruction-based detected match well with the ground truth contour, noisy. To combine best of both worlds, we present unsupervised Patch AutoEncoder-based Deep Image Decomposition (PAEDID) method segmentation. In training stage, learn common as a deep prior by patch autoencoder network. inference formulate decomposition problem sparsity regularizations. By adopting proposed approach, regions can be accurately extracted fashion. We demonstrate effectiveness PAEDID simulation studies dataset case study.

Background subtraction is a widely used concept to detect moving objects in videos taken from a static camera. In the last two decades several algorithms have been developed for background subtraction and were used in various important applications such as visual surveillance, sports video analysis, motion capture, etc.Various statistical approaches have been proposed to model scene background....
متن کاملLevel set-based histology image segmentation with region-based comparison
Automated histological grading of tissue biopsies for clinical cancer care is a challenging problem that requires sophisticated algorithms for image segmentation, tissue architecture characterization, global texture feature extraction, and high-dimensional clustering and classification algorithms. Currently there are no automatic image-based grading systems for establishing the pathology of can...
متن کاملMemory based active contour algorithm using pixel-level classified images for colon crypt segmentation
In this paper, we introduce a novel method for detection and segmentation of crypts in colon biopsies. Most of the approaches proposed in the literature try to segment the crypts using only the biopsy image without understanding the meaning of each pixel. The proposed method differs in that we segment the crypts using an automatically generated pixel-level classification image of the original b...
متن کاملPixel-Based Skin Detection for Pornography Filtering
A robust skin detector is the primary need of many fields of computer vision, including face detection, gesture recognition, and pornography filtering. Less than 10 years ago, the first paper on automatic pornography filtering was published. Since then, different researchers claim different color spaces to be the best choice for skin detection in pornography filtering. Unfortunately, no com...
متن کاملRegion-based Vessel Segmentation Using Level Set Framework
This paper presents a novel region-based snake method for vessel segmentation. According to geometric shape analysis of the vessel structure with different scale, an efficient statistical estimation of vessel branches is introduced into the energy objective function, which applies not only the vessel intensity information, but also geometric information of line-like structure in the image. The ...
