Rotate a matrix by 180 degrees. Used for adjusting image plotting in R.Glenn J Tattersall
最后我们使用180度的图片进行识别 [INFO] detected orientation: 180 [INFO] rotate by 180 degrees to correct [INFO] detected script: Latin 180度 通过以上的验证pytesseract可以较好的识别出文本方向,然后得到旋转的角度,我们便可以成功把图片给旋转到正确的方向...

Rotate a matrix by 90 degrees counterclockwise (270 degrees clockwise). Used for adjusting image plotting in R.Rotate a matrix by 90 degrees counterclockwise (270 degrees clockwise). Used for adjusting image plotting in R.Glenn J. Tattersall...
In this OpenCV tutorial, we will learn how to rotate an image to 90, 180 and 270 degrees using OpenCV Python using cv2.getRotationMatrix2D() and cv2.warpAffine() functions, with an example. OpenCV Python – Rotate Image We can rotate an image using OpenCV to any degree. ...
Rotate the image by 90 degrees (clockwise). Note: You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. 这道题就是输一个n*n的矩阵顺时针旋转90度,然后求矩阵的元素。矩阵转置是相当于旋转...

When I take a photo with the front camera, the resulting PhotoFile is rotated 90 degrees counter-clockwise. The output logs from running the example app show that the orientation is 'landscape-left', when it should use the device orientation which is portrait (or at least use theorientation...
