Public Functions Documentation

SaigeInitializeAlignModule

Function to activate the Saige Alignment function.

int SaigeInitializeAlignModule (
    const int gpuIndex,
    const int sourceWidth,
    const int sourceHeight,
    const int targetWidth,
    const int targetHeight
) 

The Alignment function adjusts the position of the Source image to match the Target image and Crop it. Therefore, the Source image must be larger than the Target image.

Parameters:

• gpuIndex This function uses the GPU, and is the index of the GPU to use.
• sourceWidth
• sourceHeight
• targetWidth
• targetHeight

Returns:

errorCode Returns 0 on success, or an error code if there is a failure.

SaigeFinalizeAlignModule

Function to terminate the Saige Alignment function. Releases the GPU memory used by the function.

int SaigeFinalizeAlignModule () 

Returns:

errorCode Returns 0 on success, or an error code if there is a failure.

SaigeAlignImageFromByteArray

Function to adjust the position of the Source image to match the Target image.

int SaigeAlignImageFromByteArray (
    const unsigned char * sourceImage,
    const int sourceWidth,
    const int sourceHeight,
    const int sourceChannel,
    const unsigned char * targetImage,
    const int targetWidht,
    const int targetHeight,
    const int targetChannel,
    unsigned int flag,
    unsigned char * croppedSourceImage
) 

The croppedSourceImage should be targetWidth * targetHeight * sourceChannel

Parameters:

• sourceImage The byte array of the Source image.
• sourceWidth The width of the Source image.
• sourceHeight The height of the Source image.
• sourceChannel The channel of the Source image.
• targetImage The byte array of the Target image.
• targetWidht The width of the Target image.
• targetHeight The height of the Target image.
• targetChannel The channel of the Target image.
• flag Whether to detect the edges of the cropped Source image.
• croppedSourceImage The byte array of the cropped Source image.

Returns:

errorCode Returns 0 on success, or an error code if there is a failure.

SaigeAlignImageFromFile

Not Implemented.

int SaigeAlignImageFromFile (
    const char * sourceImagePath,
    const char * targetImagePath,
    int * cropWidth,
    int * cropHeight,
    int * cropChannel,
    unsigned char * croppedSourceImage
)
