3.Pre-process the Image: oConvert the image to grayscale. oApply necessary image processing techniques like thresholding, blurring, or edge detection to enhance text visibility. 4.Text Detection: oUse OpenCV's
在我们开始之前,我想指出您至少需要在系统上安装OpenCV 3.4.2(或OpenCV 4)才能使用OpenCV的EAST文本检测器,因此如果您尚未安装OpenCV 3.4.2或更高版本在您的系统上,请参阅我的OpenCV安装指南。 接下来,确保您的系统上还安装/升级了imutils: pip install --upgrade imutils 此时您的系统已配置好,因此打开text_detec...
OpenCV-Python是旨在解决计算机视觉问题的Python绑定库。cv2.putText()方法用于在任何图像上绘制文本字符串。 用法:cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]]) 参数: image:它是要在其上绘制文本的图像。 text:要绘制的文本字符串。 org:它是图像中...

在开始之前,首先确保你已经安装了OpenCV库。你可以使用pip来安装OpenCV: pipinstallopencv-python 1. 绘制中文文本 在OpenCV中,我们可以使用cv2.putText()函数来在图像上绘制文本。这个函数接受多个参数,包括图像、文本内容、位置、字体、大小、颜色等。要在图像上绘制中文文本,我们需要先加载中文字体。
需求的是python2.7 tensorflow1.3 cython0.24,opencv-python,easydict,(建议安装Anaconda) (因为我有GPU)所以直接进行第三步,进入lib、utils,执行chmod+x给权限(在给权限之前,make.sh是灰色的(不可执行的文件),执行chmod+x make.sh 则变成绿色(可执行的文件)) ...
Initial image on the left, aligned image on the right First we need to import opencv: 1importcv2 Let’s read an image in. You probably will have a color image, so first we need to convert it to gray scale (one channel only). ...
Let’s see how to handle if we have an image that has multiple lines of text. It is pretty much the same; the only thing that is changed is when we print the results, we see several different lines.Hence, we need to loop through to visualize and plot each detection individually....
