field-2
Field 2 是丹麦理工大学(Technical University of Demark)的J.A.延森(Jorgen Arendt Jenson)开发的一款超声模拟软件,该软件基于线性声场理论, 其最基本概念是空间冲击响应,最早由Tupholme和Stepannishen等提出,空间冲击响应是一个和何置相关的函数,它与换能器上的激励信号卷积,可以得到发射波到焦点的任意一点的声场。换能器接收同波信号相当与发射的逆过程,将空间的反射点作为发射源,与接收换能器的空间冲击响应卷积,从而得到回波信号。(Field 2 is the Technical University of Denmark (Technical University of Demark) is an ultrasound simulation software JA Jensen (Jorgen Arendt Jenson) developed the software based on the linear sound field theory, the basic concept is the spatial impulse response, first by Tupholme and Stepannishen and other proposed space impulse response is a home-related functions and what its convolution with the excitation signal transducer, you can get any of the transmitted wave to the focal point of the sound field. Wave transducer receives a signal corresponding with the inverse process of transmission, the reflector point in space as a transmission source, and the receiving transducer spatial convolution of the impulse response, thereby obtaining the echo signal.)

vp_code_Gabor
这个代码能够比较精确地实现图像中道路区域的分割与提取。(This code addresses this question by
decomposing the road detection process into two steps: the estimation
of the vanishing point associated with the main (straight) part
of the road, followed by the segmentation of the corresponding
road area based upon the detected vanishing point. The main
technical contributions of the proposed approach are a novel
adaptive soft voting scheme based upon a local voting region using
high-confidence voters, whose texture orientations are computed
using Gabor filters, and a new vanishing-point-constrained edge
detection technique for detecting road boundaries.)
