OpenCV cvRemap Cropping Image

由 主宰稳场 提交于 2019-12-03 09:12:51
So I am very new to OpenCV (2.1), so please keep that in mind. So I managed to calibrate my cheap web camera that I am using (with a wide angle attachment), using the checkerboard calibration method to produce the intrinsic and distortion coefficients. I then have no trouble feeding these values back in and producing image maps, which I then apply to a video feed to correct the incoming images. I run into an issue however. I know when it is warping/correcting the image, it creates several skewed sections, and then formats the image to crop out any black areas. My question then is can I view

由 点点圈 提交于 2019-12-03 07:34:23
问题 I have over 1000 images on different resolutions, (for example 1234x2122, 4400x5212 , etc) and I want to convert all them to fixed 100x100 size, so. first I need to resize images keeping proportions, and get 100xA or Ax100, where A > 100 ( it depends width and height of image, for some images width > height, and for some images height > width ). Crop this image to 100x100 from center Is there a simple convert command, that I can use for all my images ? 回答1: You would use the area-fill ( ^ )

Android: Cropping an image to specific size

由 半城伤御伤魂 提交于 2019-12-03 07:18:51
问题 My intention is to have the user pick an image from the gallery, then have a cropping activity come up. However, I need the rectangle that defines the cropping mask to be locked to a certain dimension and then the user simply repositions it to display a portion of an image. Any ideas on how this would be done? Thanks -T 回答1: Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null) .setType("image/*") .putExtra("crop", "true") .putExtra("aspectX", width) .putExtra("aspectY", height)

问题 How can I crop an image in the center? Because I know that the box is a 4-tuple defining the left, upper, right, and lower pixel coordinate but I don't know how to get these coordinates so it crops in the center. 回答1: Assuming you know the size you would like to crop to (new_width X new_height): import Image im = Image.open(<your image>) width, height = im.size # Get dimensions left = (width - new_width)/2 top = (height - new_height)/2 right = (width + new_width)/2 bottom = (height + new
