mask

问题 I annotated images using PixelAnnotationTool provided here: https://github.com/abreheret/PixelAnnotationTool and using the provided dictionary: { "labels": { "unlabeled": { "categorie": "void", "color": [ 0, 0, 0 ], "id": 0, "id_categorie": 0, "name": "unlabeled" }, "bicycle_motorcycle": { "categorie": "bicycle_motorcycle", "color": [ 119, 11, 32 ], "id": 1, "id_categorie": 1, "name": "bicycle_motorcycle" }, "bus": { "categorie": "bus", "color": [ 102, 51, 0 ], "id": 2, "id_categorie": 2,

问题 According to the WC docs, if I want to add a new field in the checkout area I should write the following code in functions.php: /* Add the field to the checkout*/ add_action('woocommerce_after_order_notes', 'my_custom_checkout_field'); function my_custom_checkout_field( $checkout ) { echo '<div id="my_custom_checkout_field" class="my_new_field"><h2>' . __('My Field') . '</h2>'; woocommerce_form_field( 'my_field_name', array( 'type' => 'text', 'class' => array('my-field-class form-row-wide'),

问题 I have sign (signs with arbitrary shape) images with white background and I want to get an image of the sign with transparent background. I have managed to create a mask and apply it to the image and thought making the mask transparent would be doable. I searched a lot here and elsewhere, but nothing really helped me. import cv2 import numpy as np file_name = "/path/to/input/img/Unbenannt.jpg" # can be also .png img = cv2.imread(file_name) gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) th,

问题 Hi i'm currently writing a basic C++ application using the OpenCV library to segment the subject of the image from its background. The application reads in an image file and uses the watershed algorithm to generate a mask based on data it finds around the edges and data it finds in the centre of the image. (To start I created an image object that has an overall value of -1. Then I created a border around an empty image which has a value of 1. Then I created a rectangle roughly in the centre

问题 I have been trying to figure out what I am doing wrong when calculation the position and size of the mask rectangle once the target image has been resized. Below is the documentation from fabric JS: clipPath :fabric.Object a fabricObject that, without stroke define a clipping area with their shape. filled in black the clipPath object gets used when the object has rendered, and the context is placed in the center of the object cacheCanvas. If you want 0,0 of a clipPath to align with an object

问题 I'm trying to mask with some svg path that is created dynamically with React. The problem is that the resulted html code doesn't render properly on Chrome and Safari immediately. Correct results appear on browser window resize or check/uncheck of a style property from inspector. I feel like the problem in one of the -webkit properties but can't define which. Tried -webkit-mask , but it didn't give any results. Here's the html structure that should render right away: <div> <div id="type-1

问题 I'm trying to mask an image in swift. Here's my code: (Normally, originalImg is an image that is loaded from UIImagePickerController and then cropped by UIGraphicsGetImageFromCurrentImageContext() , and makedImage is an image that is drawn by the user, created by UIGraphicsGetImageFromCurrentImageContext() ) func imageMasking(_ originalImg: UIImage, maskImage: UIImage) -> UIImage { let cgMaskImage = maskImage.cgImage! let mask = CGImage(maskWidth: cgMaskImage.width, height: cgMaskImage.height
