1. 低阶特徵 许多影像检索技术提出利用不同的低阶特徵(low-level features)与相关的相似度比对法进行内涵式检索;然而,利用低阶特徵距 … ir.lib.isu.edu.tw|基于10个网页 2. 特征 1. 一般情况都把attribute作为中层特征(mid-level features):如下图,他介于底层特征(low-level features)和类别标签之间2. ...
hight-level feature:是建立在low level feature之上的,可以用于图像中目标或物体形状的识别和检测,具有更丰富的语义信息。 通常卷积神经网络中都会使用这两种类型的features:卷积神经网络的前几层学习Low level feature, 后几层学习的是high level feature. Quora上面也有这么一段解释: Low-level features are minor d...

1.This paper introduces the concepts of a content-based image retrieval technology and medical image retrieval system,analyzes the present research situation of medical image retrieval system,and by using multiple aspects normalized image retrieval method and the combination of low-level features and sem...
1) low-level features 底层特征1. In this paper,a new method for the object classification is proposed,in which four main low-level features are extracted from images,then a BP neural network is used in the object classification. 本文提出了提取图像的四个主要底层特征,将特征参数输入 BP 神经...
As human beings are always considered to be more intelligent than machines, languages close to the machine are called low-level languages while human-oriented programming languages are called high-level languages.doi:10.1007/978-3-642-69668-8_21Daniel Thalmann...
以下是一些常见的low-level音频特征及其提取方法：1. 时域特征 1.1 短时能量（Short-Time Energy）短...
To improve the classification performance,this article puts forward the multi level feature selection method and the kernel based distance weighted KNN algorithm. 为了提高分类性能 ,本文提出了中文文本多层次特征提取方法和基于核的距离加权KNN算法。3) Layered Features Extraction 分层次特征提取4...
This paper addresses the challenge of Multimedia Event Detection by proposing a novel method for high-level and low-level features fusion based on collective classification. Generally, the method consists of three steps: training a classifier from low-level features; encoding high-level features into...
Our method utilizes both high level and low level features for saliency detection under a unified deep learning framework. The high level features are extracted using the VGG-net, and the low level features are compared with other parts of an image to form a low level distance map. The low...
