@spec compute(t(), Evision.Mat.maybe_mat_in(), Evision.Mat.maybe_mat_in()) :: Evision.Mat.t() | {:error, String.t()}
Computes disparity map for the specified stereo pair
Positional Arguments
left:
Evision.Mat
.Left 8-bit single-channel image.
right:
Evision.Mat
.Right image of the same size and the same type as the left one.
Return
disparity:
Evision.Mat
.Output disparity map. It has the same size as the input images. Some algorithms, like StereoBM or StereoSGBM compute 16-bit fixed-point disparity map (where each disparity value has 4 fractional bits), whereas other algorithms output 32-bit floating-point disparity map.

@spec compute( t(), Evision.Mat.maybe_mat_in(), Evision.Mat.maybe_mat_in(), [{atom(), term()}, ...] | nil ) :: Evision.Mat.t() | {:error, String.t()}
Computes disparity map for the specified stereo pair
Positional Arguments
left:
Evision.Mat
.Left 8-bit single-channel image.
right:
Evision.Mat
.Right image of the same size and the same type as the left one.
Return

Python prototype (for reference):
compute(left, right[, disparity]) -> disparity
Creates StereoBM object
Keyword Arguments
numDisparities:
int
.the disparity search range. For each pixel algorithm will find the best disparity from 0 (default minimum disparity) to numDisparities. The search range can then be shifted by changing the minimum disparity.
blockSize:
int
.the linear size of the blocks compared by the algorithm. The size should be odd (as the block is centered at the current pixel). Larger block size implies smoother, though less accurate disparity map. Smaller block size gives more detailed disparity map, but there is higher chance for algorithm to find a wrong correspondence.
Return
- retval:
Evision.StereoBM
The function create StereoBM object. You can then call StereoBM::compute() to compute disparity for a specific stereo pair.
Python prototype (for reference):
create([, numDisparities[, blockSize]]) -> retval
