bounding-box

问题 Guys I am trying to query all the polygons inside by bounding box but it simply returns 0.. It should be returning many polygons! Alternatively I try to query a much larger bounding box and nothing happens! My query is: { geometry: { $geoWithin: { $box: [ [-73.995762,40.764826], [-73.934034,40.802038] ] } } } Notice that the very same query returns a valid result for geometries of type Point 回答1: to query all the polygons inside by bounding box but it simply returns 0 The $box operator for

问题 This question already has answers here : jQuery/JavaScript collision detection (6 answers) Closed 3 years ago . I have code like this: $(function() { var $selection = $('.selection'); $('li').filter(function() { var self = $(this); return /* ????? */; }).addClass('selected'); }); .widget { width: 320px; height: 200px; border: 1px solid gray; position: absolute; overflow: scroll; } .selection { position: absolute; top: 90px; left: 90px; border: 1px dotted black; height: 120px; width: 120px; }

问题 Is there a fully featured OBB class for Ogre3D? I don't think there is one by default but I am looking for an alternative which has all the features of the AxisAlignedBox class. Thanks 回答1: There are implementations around, which are not integrated in Ogre's core, since this is usually covered by physics engines and does not fall into the main area of a rendering engine: One implementation example can be found in the Ore wiki article Object Bounding Box. Its talk page, also got a few helpful

问题 Is there any easy ways to find the bounding box of a polyline using Google Maps API v3? I'm working on a project where I need to update the bounds as data is added and removed from the map. This is pretty easy by just doing bd.extend(point) where bd is the bound object and point is a LatLng object. The problem is when I start removing data I would like it to change the bounds and zoom back in. Are there any built in functions that can do this or will I need to write something for myself? 回答1:

问题 I am new to both python and Tensorflow. I am trying to run the object_detection_tutorial file from the Tensorflow Object Detection API, but I cannot find where I can get the coordinates of the bounding boxes when objects are detected. Relevant code: # The following processing is only for single image detection_boxes = tf.squeeze(tensor_dict['detection_boxes'], [0]) detection_masks = tf.squeeze(tensor_dict['detection_masks'], [0]) ... The place where I assume bounding boxes are drawn is like

问题 I can't extract the detected regions by MSER in this image: What I want to do is to save the green bounded areas. My actual code is this: import cv2 import numpy as np mser = cv2.MSER_create() img = cv2.imread('C:\\Users\\Link\\img.tif') gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) vis = img.copy() regions, _ = mser.detectRegions(gray) hulls = [cv2.convexHull(p.reshape(-1, 1, 2)) for p in regions] cv2.polylines(vis, hulls, 1, (0, 255, 0)) mask = np.zeros((img.shape[0], img.shape[1], 1), dtype

问题 I am trying to augment existing labeled bounding boxed image for making more object detection training data using the function tf.image.sample_distorted_bounding_box but I keep getting these errors found here. I'm pretty sure my bounding box is set correctly because it works when I draw the bounding box. img = mpimg.imread('bPawn0.jpg') img = img.reshape(1,300,300,3) boxes = [100,88,253,209] box = np.ones([1,1,4]) for i in range(4): box[:,:,i] = boxes[i]/300 box = tf.convert_to_tensor(box, np

问题 EDIT: I am facing a subscript problem. I managed to store the dimensions of all the bounding boxes to be created and tried using a for loop for creating bounding boxes in a row. I am using two non-zero Point3D vectors,namely center and extent , for arguments while creating the boxes. But I am getting a vector subscript out of range error while debugging. I tried the solution recommended on other questions but it's not working. Any ideas? std::vector<cetuc::BoundingBox> ObjectBox; std::vector

问题 I have some png images that I want to split it into parts, like by grid or size. But each part should have the same bounding box (transparency) as original image. Example: Splitting image into 2 parts. Original: 200 × 89 Output: part_1.png, 200 × 89 part_2.png, 200 × 89 Can ImageMagick do this? Or any other app or method. My actual goal is to split into 100+ slices images. EDIT: Another goal to have an indents for each slice. Say indent = 10px . Example: Input: 200 x 100 Output: part_1.png,

问题 I want to enclose the pair of checkboxes and the radio buttons here: ...in a rectangle or "bounding box" so that it look something like this: ...but less ugly, of course. How can I do that with the following XML as a starting point: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingLeft="@dimen/activity
