Semi-Automatic Extraction of Rural Roads under the Constraint of Combined Geometric and Texture Features

open access: yesISPRS International Journal of Geo-Information, 2021
The extraction of road information from high-resolution remotely-sensed images has important application value in many fields. Rural roads have the characteristics of relatively narrow widths and diversified pavement materials; these characteristics can ...

AN ILLUMINATION INVARIANT TEXTURE BASED FACE RECOGNITION [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2013
Automatic face recognition remains an interesting but challenging computer vision open problem. Poor illumination is considered as one of the major issue, since illumination changes cause large variation in the facial features.

Prognostic 18F-FDG Radiomic Features in Advanced High-Grade Serous Ovarian Cancer

open access: yesDiagnostics, 2023
High-grade serous ovarian cancer (HGSOC) is an aggressive disease with different clinical outcomes and poor prognosis. This could be due to tumor heterogeneity. The 18F-FDG PET radiomic parameters permit addressing tumor heterogeneity. Nevertheless, this

Textural features in flower classification

open access: yesMathematical and Computer Modelling, 2011
In this work, we investigate the effect of texture features for the classification of flower images. A flower image is segmented by eliminating the background using a threshold-based method. The texture features, namely the color texture moments, gray-level co-occurrence matrix, and Gabor responses, are extracted, and combinations of these three are ...

Deep Residual Texture Network for Terrain Recognition

open access: yesIEEE Access, 2019
In terrain recognition, the terrain image not only has texture features but also contains spatial features. However, the traditional feature descriptors mainly focus on the texture features of terrain image, ignoring the spatial features of the image ...

Multi-features fusion classification method for texture image

open access: yesThe Journal of Engineering, 2019
Aiming at the problem of poor classification and recognition rate for distorted texture image based on single texture feature, a classification method of texture image based on multi-features fusion is proposed.

Rotationally invariant texture based features [PDF]

open access: yesProceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
Content-based retrieval is ultimately dependent on the features used for the annotation of data and its efficiency is dependent on the invariance and robust properties of these features. For texture-based features an important form of invariance is rotational invariance.

Boundary-aware texture region segmentation from manga

open access: yesComputational Visual Media, 2017
Due to the lack of color in manga (Japanese comics), black-and-white textures are often used to enrich visual experience. With the rising need to digitize manga, segmenting texture regions from manga has become an indispensable basis for almost all manga
