• How to import the CascadeClassifier module from Opencv ?

  22 juillet 2015, par kylel95

  This porgram is to detect faces in the specified image. I have opencv and ffmpeg properly installed. Also, when I check the file path to see if CascadeClassifer was there, indeed it was. I somehow, still received the error :
  AttributeError : ’module’ object has no attribute ’CascadeClassifer’. I was thinking maybe it should not be called using ’cv2.CascadeClassifier’ and maybe something more lengthy. Thank you

  import cv2
  
  import numpy as np
  
  
  
  face_cascade = cv2.CascadeClassifer('haarcascade_frontalface_default.xml')
  
  eye_cascade = cv2.CascadeClassifier('haarcascade_eye.xml')
  
  
  
  image = cv2.imread('image.png')
  
  gray = cv2.cvtColor(image, cv2.COLOR_RGB2GRAY)
  
  
  
  faces = face_cascade.detectMultiScale(gray, 1.3, 5)
  
  for (x,y,w,h) in faces:
  
     cv2.rectangle(image,(x,y),(x+w,y+h), (225,0,0),2)
  
     roi_gray = gray[y:y+h, x:x+w]
  
     roi_color = image[y:y+h, x:x+w]
  
     eyes = eye_cascade.detectMultiScale(roi_gray)
  
     for (ex,ey,ew,eh) in eyes:
  
         cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)
  
  
  
  cv2.imshow('Imgae', image)
  
  cv2.waitKey(0)
  
  cv2.destroyAllWindows()

• Set the width of text in FFMPEG

  7 juin 2020, par Super Gadgets

  I am currently stuck with ffmpeg issue, I have an online video editor where users can add text and edit it.

  



  So I make an overlay div over the tag to let the user see exactly what the video will look like after render.

  



  But here is the issue : How can I get the css and let ffmpeg apply it on the text, the css will be the div where the transcription is how width, height , margins , colors ...

  



  Here is an example of a box :

  



  <div style="width:100px;text-align:center;top:10px;left:10px> TEXT HERE <div>&amp;#xA;

  &#xA ;&#xA ;

  P.s : I tried Aegisub, force_style but no options seems to offer setting the width of the box.

  &#xA ;&#xA ;

  Is there any way to do this ? Thank you.
