The distance transform operator generally takes binary images as inputs. In this operation, the gray level intensities of the points inside the foreground regions are changed to distance their respective distances from the closest 0 value (boundary). You can apply distance transform in OpenCV using the method distanceTransform(). Following is the syntax of this method.

Type of distance, see DistanceTypes: maskSize: Size of the distance transform mask, see DistanceTransformMasks. In case of the DIST_L1 or DIST_C distance type, the parameter is forced to 3 because a \(3\times 3\) mask gives the same result as \(5\times 5\) or any larger aperture. dstType: Type of output image. It can be CV_8U or CV_32F.

JULIO C. TORELLI and ODEMIR M. BRUNO Instituto de Ciˆencias Matem´aticas e de Computa¸c˜ao, USP The distance transform (DT) is a general operator forming the basis of many methods in computer vision and geometry, with great potential for practical applications. However, all the optimal algorithms for the

A distance transform, also known as distance map or distance field, is a derived representation of a digital image. The choice of the term depends on the point of view on the object in question: whether the initial image is transformed into another representation, or it is simply endowed with an additional map or field. Distance fields can also be signed, in the case where it is important to distinguish whether the p…

Use the OpenCV function cv::watershed in order to isolate objects in the image from the background.

C A; simply represents an arbitrary a ne transformation, having 12 degrees of freedom. These degrees of freedom can be viewed as the nine elements of a 3 3 matrix plus the three components of a vector shift. The most important a ne transformations are rotations, scalings, and translations, and in fact all a ne transformations can be expressed
