| 2015-07-11 05:53:14 -0600 | asked a question | find new coords of camera Hello guys I would like to find the coordinates (x and y offsets) and the rotation angle of a camera. I'll explain. I have a camera looking from the top down The camera will move in the x and y. The camera does not move in z (height / or depth) The camera may rotate with the axis z (always looking down) After you have moved / rotated I understand what has moved (dx and dy) and possibly how many degrees you have rotated. How would I go? of course I would go to compare the current image with the previous image. I thought I'd get the image to look like pulling portion from the previous image, and use surf to look for in the new image (current image). I've also done, but it is very laborious. Is there another way? thanks PS sorry I used google translator |

| 2015-06-27 11:04:07 -0600 | asked a question | find bounding box of the image Hello everybody I have to find the min coord and max coord of this image. (see the red rectangle of the image) How can I do? I know the color is white (255) I made an algorithm but it is too slow. There is a native method of open cv. Thank you all. |
| 2015-06-24 04:47:01 -0600 | answered a question | Fill irregular area hi guy :) i resolved this is the code for visual basic Dim ImgStor As MemStorage Dim seedPoint As Point = New Point(0, 0) Dim cc As Emgu.CV.Structure.MCvConnectedComp CvInvoke.cvFloodFill(img, seedPoint, New MCvScalar(0, 0, 0), New MCvScalar(100, 100, 100), New MCvScalar(100, 100, 100), cc, 4, ImgStor) Me.Text = cc.area PictureBox1.Image = img.ToBitmap I hope will be of help to others. |

| 2015-06-18 03:52:25 -0600 | asked a question | Fill irregular area Hello I wanted to ask if you could please help me. I have to fill an area as shown in Figure (img1.jpg) https://www.dropbox.com/s/hvgjmyvcw9z... and get img2.jpg https://www.dropbox.com/s/kpccy42w0ps... I have to fill only the top I filled until I find a white color. I also have to count how many pixels are green E 'can do such a thing with opencv? I use vb2010 with emgu, but that's okay with c # and opencv. Sorry for my English I used ul online translator Grazie |
