* @brief Calculate Radon Transform of an image.
|
||
|
|
* @param src The source (input) image.
|
||
|
|
* @param dst The destination image, result of transformation.
|
||
|
|
* @param theta Angle resolution of the transform in degrees.
|
||
|
|
* @param start_angle Start angle of the transform in degrees.
|
||
|
|
* @param end_angle End angle of the transform in degrees.
|
||
|
|
* @param crop Crop the source image into a circle.
|
||
|
|
* @param norm Normalize the output Mat to grayscale and convert type to CV_8U
|
||
|
|
*
|
||
|
|
* This function calculates the Radon Transform of a given image in any range.
|
||
|
|
* See https://engineering.purdue.edu/~malcolm/pct/CTI_Ch03.pdf for detail.
|
||
|
|
* If the input type is CV_8U, the output will be CV_32S.
|
||
|
|
* If the input type is CV_32F or CV_64F, the output will be CV_64F
|
||
|
|
* The output size will be num_of_integral x src_diagonal_length.
|
||
|
|
* If crop is selected, the input image will be crop into square then circle,
|
||
|
|
* and output size will be num_of_integral x min_edge.
