We use Pytesseract + OpenCV to build a simple ocr system on colab
This is for colab's simple ocr sample,please copy it or put it in your Google Drive than you can open it.
Clone from my github
git clone https://github.com/tingruikp0925/simpleocr.git
After you upload the picture for this sample You can Read/Resize/Flip/Rotate or cvtColor via use cv2 package.
Follow this information and change the config you need.
Read：cv2.imread(filename, flags)
Show：cv2.imshow(window_name, image)
Save：cv2.imwrite(save_filename, image)
Resize：cv2.resize(image, size, interpolation)
Flip：cv2.flip(image, flipCode)
Rotate： M = cv2.getRotationMatrix2D(rotate_center, rotate_angle, ratio) rot_img = cv2.warpAffine(image, M, size)
CvtGray: cv2.cvtColor(image, colorspace_num=7)
