Changes

• Validate possible keyword arguments for functions that accept named arguments.

  iex> img = Evision.imread("test/testdata/dog.jpg")
  
  # valid keyword argument
  iex> Evision.applyColorMap(src: img, colormap: Evision.Constant.cv_COLORMAP_AUTUMN)

  }
  
  # list all possible keyword arguments if the user provides any invalid ones
  iex> Evision.applyColorMap(src: img, colorMap: Evision.Constant.cv_COLORMAP_AUTUMN)

• Generated typed enums for OpenCV's cv::flann.

• This should include the following enums and place them in the corresponding modules.

  • flann_algorithm_t
  • flann_centers_init_t
  • flann_log_level_t
  • flann_distance_t
  • flann_datatype_t

  For example, flann_algorithm_t will be put in the Evision.Flann.Algorithm module:

  defmodule Evision.Flann.Algorithm do
    @type enum :: integer()
    @doc enum: true
    def cv_FLANN_INDEX_LINEAR, do: 0
    @doc enum: true
    def cv_FLANN_INDEX_KDTREE, do: 1
    @doc enum: true
    def cv_FLANN_INDEX_KMEANS, do: 2
    @doc enum: true
    def cv_FLANN_INDEX_COMPOSITE, do: 3
    @doc enum: true
    def cv_FLANN_INDEX_KDTREE_SINGLE, do: 4
    @doc enum: true
    def cv_FLANN_INDEX_HIERARCHICAL, do: 5
    @doc enum: true
    def cv_FLANN_INDEX_LSH, do: 6
    @doc enum: true
    def cv_FLANN_INDEX_SAVED, do: 254
    @doc enum: true
    def cv_FLANN_INDEX_AUTOTUNED, do: 255
  end

v0.2.2

Changelog

v0.2.2 (2024-06-15)

Browse the Repository | Released Assets

Added

• Experimental support for CUDA shared memory via Evision.CUDA.GpuMat.to_pointer/{1,2}.
• Experimental support for Gleam. See gleam_evision_demo for more information.

Changes

• General improvements to the typespecs. Enumerators now also have their own modules.

• Experimental support for using Nx.tensor directly without calling helper functions like Evision.Mat.from_nx/1, Evision.Mat.from_nx_2d/1 and Evision.Mat.last_dim_as_channel/1 .

• Support /AOS (arithmetic op src) marks in OpenCV source code.

  This should make evision's behaviour in line with OpenCV (C++ and Python).

  For example, in Evision.add/2, the expected behaviour should be different when src1/src2 are single number and they are tuple/array.

  add(src, X) where X is a number (or Nx.tensor(X)), it means add(src, {X,X,X,X})

  while add(src, {X}) (or add(src, Nx.tensor([X]))) means add(src, {X,0,0,0}).

• Allow a single number to be passed as Evision.Mat.maybe_mat_in() and Evision.scalar().

• Allow a n-tuple (containing n numbers) to be passed as Evision.Mat.maybe_mat_in() and Evision.scalar().

• Evision.Mat now implements Nx.LazyContainer protocol.

Fixes

• Fixed Erlang bindings when converting from Elixir structs to Erlang records and vice versa.
