-* @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.

+ * @brief Computes the Radon transform of a given 2D image.
+ *
+ * The Radon transform is often used in image processing, particularly in applications
+ * like computed tomography, to analyze the structure of an image.
+ *
+ * @param src The input image on which the Radon transform is to be applied.
+ *            Must be a 2D single-channel array (e.g., grayscale image).
+ * @param dst The output array that will hold the result of the Radon transform.
+ * @param theta The angle increment in degrees for the projection.
+ * @param start_angle The starting angle for the Radon transform in degrees.
+ * @param end_angle The ending angle for the Radon transform in degrees.
+ *                  The difference between end_angle and start_angle must be positive when multiplied by theta.
+ * @param crop A flag indicating whether to crop the input image to a square or circular shape before transformation.
+ * @param norm A flag indicating whether to normalize the output image to the range [0, 255] after computation.
