  • New
    • Function Version() on Python interface - returning Smil Version
  • Change
    • Remove dependencies on X86 and Linux, to be able to run on other architectures and operating systems.
  • Bug
    • Bug on function fromNumpyArray() which works only on 3D images.

Smil 1.1 (14 May 2024)

  • New
    • Structuring elements CenteredLineSE() and CenteredLine3DSE() created in complement to LineSE() and Line3DSE()
    • functions rectangleDilate(), rectangleErode(), rectangleOpen() and rectangleClose(). Generic functions based on line morphology.
  • Change
    • In functions LineSE() and Line3DSE(), angle units changed from degres do radians.
    • function stretchHist() renamed to stretchHistogram().)
    • function fastLambdaLabel() removed as its results are wrong. Use function lambdaLabel() which gives correct results.
    • Option –imagetypes to define data types for gray images. Default values is UINT8;UINT16;UINT32
    • A plugin Samg was added with functions from old Chabardes plugin. These functions are needed by Samg functions. The aren't documented.
    • Experimental code to do SIMD parallel processing was removed as it is specific to Intel processors. Better use OpenMP feature for this.
  • Bug
    • Deprecated function in Numpy API, since release 1.19. New code needs release 1.15 or newer.
    • Problems when getting the cardinality of values in UINT32 images in the cardinality() function.
    • Attribute opening/closing based on MaxTree - Problem with memory allocation on MaxTree limiting the size of image being handled.
    • circleErode() and circleDilate() - functions based on line StrElt doesn't match expected radius. Improved but still not perfect.
    • some warnings about Qt deprecated functions.
  • Documentation
    • minor error corrections and adaptation to the above changes.

Smil 1.0.3 (15 Jan 2024)

Smil 1.0.0 (30 Sep 2022)

  • New
    • Functions :
