So the question is - how to use fn.crop function to crop many images from original image? How to pass a list of coordinates into fn.crop?ĭummy_img = np.random.randint(2, size=(1, 1920, 1080))Įii = ExternalInputIterator(image=dummy_img, persons=np.expand_dims(np.array(, dtype=np.float32), num_threads=4, device_id=0) It works fine for one person (when I use crop_pos_x=persons_list/1920, crop_pos_y=persons_list/1080 instead of crop_pos_x=persons_list/1920, crop_pos_y=persons_list/1080, for example), but how to pass list of coordinates to crop to cut multiple bboxes from image?Īccording DALI documentation it is possible, for example, crop_pos_x (float or TensorList of float, optional, default = 0.5). I try to crop a one big image with some count of persons on it using fn.crop operation with parameters crop_pos_x and crop_pos_y. ![]() That is why I read it from fn.external_source along with an image. The point is that the batch depends on the number of people in the frame - it is always different, dynamic. Then a batch is formed from these cropped out detections and fed into the hrnet48 network. Object detections are then cropped from the main image. Notice that I put no effort at all into making sure the images were positioned properly on the scanner (they're all crooked).I'm trying to prepare preprocessing pipeline for MMPose network - specifically for hrnet48.įor mmpose operation, an additional object detector is used. Here's my file after scanning four images at once. Save your file in the TIFF format for best image quality, then open it in Photoshop.ĭownload this tutorial as a print-ready PDF! Photoshop isn't capable of actually scanning images, so you'll need to use either the software your scanner came with or a third party program like VueScan or SilverFast to scan the photos. First, place as many photos as you'd like (or at least, as many as you can fit) onto your scanner, making sure to leave some empty space around each one so they don't overlap. With it, we can scan multiple images at once with our flatbed scanner, then let Photoshop automatically crop them, straighten them and open each photo for us in its own separate document, all in a matter of seconds! Of course, with no shortage of old photos lying around and a serious shortage of spare time, scanning, cropping and straightening each image individually can take too long.įortunately, there's no need to do that thanks to an amazing feature first introduced back in Photoshop CS, the Crop and Straighten Photos command. One of the things I love to do in my spare time is digitize old photos, scanning them into my computer so I can retouch them in Photoshop, then printing off newly restored versions of them or just saving them to CD or DVD for safekeeping. ![]()
