Projection Merging: Reducing Redundancies in Inclusion Constraint Graphs
Projection Merging Reducing Redundancies Inclusion Constraint Graphs
2016/5/24
Inclusion-based program analyses are implemented by adding new edges to directed graphs. In most analyses, there are many di erent ways to add a transitive edge between two nodes, namely through each ...
Trinary-Projection Trees for Approximate Nearest Neighbor Search
Approximate nearest neighbor search KD trees trinary-projection trees
2016/1/23
We address the problem of approximate nearest neighbor (ANN) search for visual descriptor indexing. Most spatial partition trees, such as KD trees, VP trees and so on, follow the hierarchical binary s...
Relaxed Cross-lingual Projection of Constituent Syntax
Relaxed Cross-lingual Projection Constituent Syntax
2013/4/22
We propose a relaxed correspondence as-sumption for cross-lingual projection of con-stituent syntax, which allows a supposed constituent of the target sentence to corre-spond to an unrestricted treele...
Effective Constituent Projection across Languages
Effective Constituent Projection across Languages
2013/4/22
We describe an effective constituent pro-jection strategy, where constituent pro-jection is performed on the basis of de-pendency projection. Especially, a novel measurement is proposed to evaluate th...
Does Touching a Projection Augmented Model and Interacting with it using a Spatially-Coincident Device, Affect a User's Perception of its Size?
Projection Augmented models haptic Tangible User Interface

A Projection Augmented model (PA model) is a novel type of display. It consists of a real physical model, onto which a computer image is projected to create a realistic looking object. PA models pro...
基于图像旋转投影的导航路径检测算法（Navigation Line Detection Arithmetic Based on Image Rotation and Projection）
联合收获机 自动导航 图像处理

提出一种农业车辆视觉导航路径识别算法——旋转投影算法。该算法通过角度枚举对图像ROI实施旋转变换，由旋转后图像的列均值与枚举角度构成旋转投影矩阵R，对其行向量实施差分运算得到差分旋转投影矩阵Rd，由Rd的极值可确定图像导航路径，即航向偏差θ与航位偏差d，进而可以求得世界坐标系下的导航路径参数。同理可以对田头线进行检测。为了提高算法的实时性，提出设定合理的ROI、实施线性压缩、旋转角度先粗分再细分的...

Classifiability-Based Optimal Discriminatory Projection Pursuit
2013/7/17
Linear Discriminant Analysis (LDA) might be the most widely used linear feature extraction method in pattern recognition. Based on the analysis on the several limitations of traditional LDA, this pape...

Manifold Learning Dimensionality Reduction Supervised Learning Discriminant Analysis
2014/3/11
A new algorithm, Laplacian MinMax Discriminant Projection (LMMDP), is proposed in this paper for supervised dimensionality reduction. LMMDP aims at learning a discriminant linear transformation. Speci...
