Detailed Description

Python Wrapper of Simd Library.

Function Documentation

AbsGradientSaturatedSum()

Image AbsGradientSaturatedSum	(	Image	src,
		Image	dst
	)

Gets 8-bit gray image saturated sum of absolute gradient for every point of source 8-bit gray image.

Parameters

src	- an input 8-bit gray image.
dst	- an output 8-bit gray image with sum of absolute gradient. Can be empty.

Returns

- output 8-bit gray image with sum of absolute gradient.

Resize()

def Resize	(	Image	src,
		Image	dst,
			method = Simd.ResizeMethod.Bilinear
	)

The function performs image resizing.

Parameters

src	- an original input image.
dst	- a resized output image.
method	- a resizing method. By default it is equal to Simd.ResizeMethod.Bilinear.

Resized()

Image Resized	(	Image	src,
		int	width,
		int	height,
			method = Simd.ResizeMethod.Bilinear
	)

The function gets resized image.

Parameters

src	- an original input image.
width	- a width of output image.
height	- a height of output image.
method	- a resizing method. By default it is equal to Simd.ResizeMethod.Bilinear.

Returns

- resized output image.

SynetSetInput()

def SynetSetInput	(	Image	src,
		array.array('f')	lower,
		array.array('f')	upper,
		ctypes.c_void_p	dst,
		int	channels,
		Simd.TensorFormat	format,
			isRgb = False
	)

Sets image to the input of neural network of Synet Framework.

Parameters

src	- an input image. There are following supported pixel format: aSimd.PixelFormat.Gray8, Simd.PixelFormat.Bgr24, Simd.PixelFormat.Bgra32, Simd.PixelFormat.Rgb24, Simd.PixelFormat.Rgba32.
lower	- an array with lower bound of values of the output tensor. The size of the array have to correspond number of channels in the output image tensor.
upper	- an array with upper bound of values of the output tensor. The size of the array have to correspond number of channels in the output image tensor.
dst	- a pointer to the output 32-bit float image tensor.
channels	- a number of channels in the output image tensor. It can be 1 or 3.
format	- a format of output image tensor. There are supported following tensor formats: Simd.TensorFormat.Nchw, Simd.TensorFormat.Nhwc.
isRgb	- is channel order of output tensor is RGB or BGR. Its default value is false.

WarpAffine()

def WarpAffine	(	Image	src,
		array.array('f')	mat,
		Image	dst,
			flags = (Simd.WarpAffineFlags.ChannelByte | Simd.WarpAffineFlags.InterpBilinear | Simd.WarpAffineFlags.BorderConstant),
			border = array.array('B', [])
	)

Performs warp affine for current image.

Parameters

src	- an input image to warp affine.
mat	- a pointer to 2x3 matrix with coefficients of affine warp.
dst	- a background input/output image.
flags	- a flags of algorithm parameters. By default is equal to Simd.WarpAffineFlags.ChannelByte | Simd.WarpAffineFlags.InterpBilinear | Simd.WarpAffineFlags.BorderConstant.
border	- an array with color of border. The size of the array must be equal to channels. It parameter is actual for Simd.WarpAffineFlags.BorderConstant flag.
