pshapedesign

Synopsis

Description

pshapedesign creates a new image from the specified dimensions (width, height, depth) with a synthetic shape. The parameter type determines the number of the shape type. The background is set to 0 and the shape is set to 255. Shapes are oriented vertically.

The center of the shape is center in the image. Height, width and depth of the shape are deduced from the diameter and the length parameters.

Parameters

• width,height,depth specify the dimension of the new image, respectively the width, the height, and the depth. If depth=0 then the output image is a 2D image, and if h=0 then the output image is a 1D image.
• type determines the shape type:

  2D

  • 0- empty
  • 1- disc
  • 2- square
  • 3- rectangle

    3D

  • 10- empty
  • 11- sphere
  • 12- cube
  • 13- parallelepiped
  • 14- cylinder
  • 15- bipyramid
• diameter specifies the diameter of a symmetrical shape, or the height and depth of an asymmetrical shape.
• length specifies the length of asymmetrical shape. For symmetrical shape, length is ignored.

Outputs

• im_out: a gray level image of Uchar (Img2duc or Img3duc).

Result

Returns SUCCESS or FAILURE.

Examples

Builds a synthetic image (a square) to illustrate the Gibbs phenomenon in wavelets analysis.
