【OpenCV学习笔记 010】提取直线、轮廓及连通区域
- 关于OPENCV图像分割后图像连通问题,具体可以查看源代码(OPENCV image segmentation on the image connectivity problem, you can view the source code)
colorMom
- 颜色矩是一种简单有效的颜色特征表示方法,有一阶矩(均值,mean)、二阶矩(方差,viarance)和三阶矩(斜度,skewness)等,由于颜色信息主要分布于低阶矩中,所以用一阶矩,二阶矩和三阶矩足以表达图像的颜色分布,颜色矩已证明可有效地表示图像中的颜色分布。本代码很好的实现了对图片颜色矩的提取,并有详细的注释。(Color moment is said a simple and effective method of color feature, a moment (mean, mean)
二维图像卷积代码
- 提取二维卷积特征,需要先对视频进行分帧,然后再对视频帧进行二维卷积(To extract two-dimensional convolution features, we need to segment the video first, and then two-dimensional convolution of the video frame)
HOG
- 求取任意图片的HOG特征,一共提取360个梯度特征,可用于ADABoost,SVM中。(Seek the HOG feature of any picture)
keypoint
- 对非平稳信号进行分段、截取,再对处理过后的短时信号做短时傅里叶变换,分析其频谱特性,并找到各个时间节点的频率特性,以便分析不同事件段内的声音特征,以图像的形式表达出,最终达到区分不同声音的目的。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysi
graycopropswy
- 自己编写的一个小程序,主要用于图像的灰度特征提取(Gray feature extraction for image)
code1
- 特征点提取及图像匹配,局部图像特征提取匹配(Feature point extraction and image matching, local image feature extraction matching.)
LCD&OV7725
- 使用stm32f4搭载ov7725,进行图像读取与数据处理,能稳定显示在lcd显示屏上,并且提取黑线(The use of stm32f4 equipped with ov7725, image reading and data processing, can be stably displayed on the LCD display, and extract black lines)
uvineanq
- 以matlab实现数字水印的生成和提取,用的是高斯随机序列(With matlab the generation and extraction of digital watermarking, using a gaussian random sequences)
Gabor提取图像纹理
- Gabor实现图像纹理特征提取,用于人脸识别,指纹识别等,并用matlab进行编码。(Gabor complete image texture feature extraction)
przgyammer
- 采用matlab编写的角点提取程序,可以方便的提取几何图像的所有角点(Using matlab corner extraction procedure, easy to extract all the corner point geometry image)
OpenCV_ImageBackgroundRemoval-master
- 把简单背景图像过滤掉,只保留前景图像,太过于复杂的背景,比如森林街道效果会非常差(Filter out the simple background image)
航拍绝缘子识别
- 基于opencv的图像识别,主要识别并提取绝缘子。 也可应用于其他物体的识别。(Opencv based image recognition, mainly identify and extract insulators. It can also be applied to the recognition of other objects.)
基于opencv的绝缘子及其等电位线故障状态智能识别
- 识别复杂背景下的绝缘子,提取绝缘子,放射投影后对绝缘子进行故障检测。(To identify the insulator in the complex background, the insulator is extracted and the insulator is detected after the projection.)
基于高斯尺度空间GHT的绝缘子识别方法
- 主要用高斯函数提取物体的形状来识别绝缘子,绝缘子是圆形或者椭圆,也可能倾斜,受环境因素影响。(Using gaussian functions to identify insulators, insulators are circular or elliptical, and may be tilted, influenced by environmental factors.)
test5
- 基于图像处理的方法实现车牌图像的矫正和提取(Realization and Extraction of License Plate Image Based on Image Processing)
KSVD算法
- 是图像复原算法KSVD,用于图像的特征提取,效果比其他方法好。(Is the image restoration algorithm KSVD, for image feature extraction, the effect is better than other methods)
tuxiangjiansuo
- 本代码为计算HSV直方图代码,可以在图像检索时,作为颜色特征来使用。(This code for the calculation of HSV histogram code, you can use in image retrieval as a color feature.)
