Collaboration diagram for Snake:
Public Member Functions | |
| Snake (QtCvWrapper *parent, IplImage *inImg) | |
| constructor of the snake class | |
| virtual | ~Snake (void) |
| destructor | |
| bool | setInImg (IplImage *inImg) |
| sets the input image for the snake algorithm | |
| IplImage * | getInImg () |
| returns the actual input image for snake algorithm | |
| IplImage * | getSnakeImage () |
| returns actual snake image | |
| void | initSnakeCurve () |
| initializes a first version of the curve | |
| void | initSnakeCurve (CvPoint *pt) |
| initialize a special snake curve | |
| IplImage * | iterateSnakeCurve (int numIterations, bool showIterations) |
| tries to approximate the contour curve with numIterations | |
Private Attributes | |
| QtCvWrapper * | m_parent |
| parent that sets connection to the "outside" | |
| IplImage * | m_inImg |
| IplImage * | m_snakeImg |
| input Image | |
| CvTermCriteria | m_crit |
| image with the snake included | |
| CvPoint * | m_snakeCurve |
| stopping criteria | |
| float | m_alpha |
| curve that represents the snake | |
| float | m_beta |
| Weight of continuity energy, single float or array of length floats, one per each contour point. | |
| float | m_gamma |
| Weight of curvature energy, similar to alpha. | |
| CvSize | m_winSize |
| Weight of image energy, similar to alpha. | |
| int | m_numSegments |
| Size of neighborhood of every point used to search the minimum (use odd numbers!). | |
| int | m_numIteration |
| number of segments the snake curve is divided | |
The snake class implements the snake algorithm from the OpenCV library. cvSnakeImage is called within an iteration until the maximum number of iteration is reached or the error reaches a certain minimum.
| parent | is just the connection to the application that makes use of the Snake class | |
| inImg | represents the initial image for Snake segmentation |
alpha, beta and gamma could be vectors -> make it configurable
