SEGMENTATION OF LARGE UNSTRUCTURED POINT CLOUDS USING OCTREE-BASED REGION GROWING AND CONDITIONAL RANDOM FIELDS
Segmentation Region Growing Conditional Random Fields Point Clouds
font style='font-size:12px;'>
2018/3/5
Point cloud segmentation is a crucial step in scene understanding and interpretation. The goal is to decompose the initial data into sets of workable clusters with similar properties. Additionally, it...
REGULARIZATION, ADAPTATION, AND NON-INDEPENDENT FEATURES IMPROVE HIDDEN CONDITIONAL RANDOM FIELDS FOR PHONE CLASSIFICATION
Hidden Conditional Random Fields Speech Recognition Phone Classification Maximum a Posteriori
font style='font-size:12px;'>
2015/6/12
We show a number of improvements in the use of Hidden Conditional Random Fields (HCRFs) for phone classification on the TIMIT and Switchboard corpora. We first show that the use of regularization effe...

CLASSIFICATION OF AIRBORNE LASER SCANNING DATA IN WADDEN SEA AREAS USING CONDITIONAL RANDOM FIELDS
LiDAR classification conditional random fields coast
font style='font-size:12px;'>
2014/4/28
In this paper we investigate the influence of contextual knowledge for the classification of airborne laser scanning data in Wadden Sea areas. For this propose we use Conditional Random Fields (CRF) f...
Loss-sensitive Training of Probabilistic Conditional Random Fields
Loss-sensitive Training Probabilistic Conditional Random Fields
font style='font-size:12px;'>
2011/7/19
We consider the problem of training probabilistic conditional random fields (CRFs) in the context of a task where performance is measured using a specific loss function. While maximum likelihood is th...
CONDITIONAL RANDOM FIELDS FOR THE CLASSIFICATION OF LIDAR POINT CLOUDS
Conditional Random Fields 3D Point Cloud LiDAR Classification
font style='font-size:12px;'>
2014/6/5
In this paper we propose a probabilistic supervised classification algorithm for LiDAR (Light Detection And Ranging) point clouds.
Several object classes (i.e. ground, building and vegetation) ca...
MULTITEMPORAL CROP TYPE CLASSIFICATION USING CONDITIONAL RANDOM FIELDS AND RAPIDEYE DATA
Crop Agriculture Classification Multitemporal Satellite
font style='font-size:12px;'>
2014/6/5
The task of crop type classification with multitemporal imagery is nowadays often done applying classifiers that are originally
developed for single images like support vector machines (SVM). These...
Profile conditional random fields for modeling protein families with structural information
sequence analysis structure prediction fold recognition dynamic programming mean field approximation
font style='font-size:12px;'>
2010/12/2
A statistical model of protein families, called profile conditional random fields (CRFs), is proposed. This model may be regarded as an integration of the profile hidden Markov model (HMM) and the Fin...

font style='font-size:12px;'>
2015/1/24
Morpheme analysis is very important for Uyghur language processing. Morpheme analysis
of Uyghur is quite different from other language, for this task the keys include feature
selection and the des...
Semi-supervised Learning for Image Annotation Based on Conditional Random Fields（图）
Image Annotation Conditional Random Fields
font style='font-size:12px;'>
2015/1/24
Automatic image annotation (AIA) has been proved to be an effective and promising solution to automatically deduce the high-level semantics from low-level visual features. Due to the inherent ambiguit...
