2016-07-29 20:24:52 -0600 | asked a question | what is "public camera_activity() { }"? public camera_activity() { " public camera_activity() { }" is deprecated? I can see " public camera_activity() { }" in old android source code I am using opencv 3.1 for android what is " public camera_activity() { }" ? |

2016-07-28 13:14:42 -0600 | commented question | "core.ellipse" has error I am using opencv 3.1 for android. I found "core.ellipse" in old source. How can I make right source that works well like app using "core.ellipse" in opencv old version. |
2016-07-28 07:29:02 -0600 | asked a question | "core.ellipse" has error How can I solve error? "core.ellipse" has error like below but core.ellipse have api doc ===>http://docs.opencv.org/java/2.4.2/org/opencv/core/Core.html#ellipse(org.opencv.core.Mat, org.opencv.core.Point, org.opencv.core.Size, double, double, double, org.opencv.core.Scalar)ellipse public static void ellipse(Mat img, RotatedRect box, Scalar color, int thickness) Draws a simple or thick elliptic arc or fills an ellipse sector. The functions ellipse with less parameters draw an ellipse outline, a filled ellipse, an elliptic arc, or a filled ellipse sector. A piecewise-linear curve is used to approximate the elliptic arc boundary. If you need more control of the ellipse rendering, you can retrieve the curve using "ellipse2Poly" and then render it with "polylines" or fill it with "fillPoly". If you use the first variant of the function and want to draw the whole ellipse, not an arc, pass startAngle=0 and endAngle=360. The figure below explains the meaning of the parameters. Figure 1. Parameters of Elliptic Arc Parameters: img - Image. box - Alternative ellipse representation via "RotatedRect" or CvBox2D. This means that the function draws an ellipse inscribed in the rotated rectangle. color - Ellipse color. thickness - Thickness of the ellipse arc outline, if positive. Otherwise, this indicates that a filled ellipse sector is to be drawn. See Also: org.opencv.core.Core.ellipse |
