Collision Detection using bounded boxes

时光毁灭记忆、已成空白 提交于 2020-02-03 08:16:47
问题 I'm doing a programing project for class. We are programing the game break out, which consist of a ball, a paddle, four edges, and bricks. the ball bounces off the different objects and each object preforms different operations upon itself when a collision is detected. below is my code which currently doesn't work. I'm trying to use the location of the object (its center point) to construct a bounded box and the values of each edge(Top, Bottom, Left, Right) to calculate if the boxes hit. I

How to detect paragraphs in a text document image for a non-consistent text structure in Python

问题 I am trying to identify paragraphs of text in a .pdf document by first converting it into an image then using OpenCV. But I am getting bounding boxes on lines of text instead of paragraphs. How can I set some threshold or some other limit to get paragraphs instead of lines? Here is the sample input image: Here is the output I am getting for the above sample: I am trying to get a single bounding box on the paragraph in the middle. I am using this code. import cv2 import numpy as np large = cv2

Find rightmost/leftmost point of SVG path

梦想的初衷 提交于 2020-01-26 04:16:05
问题 How to find leftmost/rightmost point of SVG C (bezier curve) path segment? I know there is getBoundingClientRect() and getBBox() but none of them apply since they return only single coordinate of the point. Just to avoid XY problem - I want to split single path composed of bezier curves into several paths each monotonously going from left to right (or right to left). It means that on any single path should be no 2 points having equal X coordinate. I understand that required split point may

Problems plotting with Octave

删除回忆录丶 提交于 2020-01-24 17:27:29
问题 I've just started using Octave. When I start octave and try to plot something, the plot works but I get the following warnings repeated many times: warning: ft_render: unable to load appropriate font warning: ft_render: invalid bounding box, cannot render More warnings appear if I click and drag the plot or even mouse-over it. If I then try to add an xlabel or title, I get a segfault and octave quits. The default graphics_toolkit is fltk, which I found by starting octave and running graphics

How to get ROI Bounding Box Coordinates without Guess & Check

拜拜、爱过 提交于 2020-01-15 05:58:49
问题 So I am attempting to take a screenshot of my monitor and only grab part of the screen when doing so. I know I can use mss or opencv, pillow or any other screenshotting library that supports bounding boxes... However, instead of randomly guessing on what the coordinate are... and what I mean by this is taking a screenshot with bounding box coordinates set, and seeing if it is anywhere close to what I am actually trying to get the picture of. For example: my trial coordinates would be 10,10

SFML Bounding Box Collision Detection

故事扮演 提交于 2020-01-13 18:55:16
问题 I am trying to write a very basic game for my first SFML project. Its a robot with a jointed arm that will be able to pop balloons with his hand only. The problem I am having is that when checking to see if the pincer sprite intersects with the balloon sprite , it returns true all the time, regardless of the placement of the balloon or the robot pincer. I am using transform to place the various parts of the robot arm, and this is whats causing the problem I think, but I don't know why. I have

Sort bounding boxes with Tl() : Opencv Android

耗尽温柔 提交于 2020-01-06 13:12:08
问题 I am trying to sort the bounding boxes with y axis and then x axis but the results I find from tl().x and tl().y are bit confusing and after lot of work I couldn't find anything in documentation. Here are some results please take a look. I want them to be in order from 1 to 30 CODE: m = Utils.loadResource(MainActivity.this, R.drawable.sheet1, Highgui.CV_LOAD_IMAGE_COLOR); //Mat original = Utils.loadResource(MainActivity.this, R.drawable.sheet1, Highgui.CV_LOAD_IMAGE_COLOR); Bitmap bm = Bitmap
