• edge

v1.15.1+rc1

#19

v1.15.0

#18

ZNCC

• improve performance ZNCC
• add prepared ZNCC template
• minior imporoved performacne SAD/SSD/NCC

v1.14.0

#17

• implemented ZNCC (not tuned yet)
• add PreparedNCC

v1.13.1

• NCC score float32 to double(avoid NaN)
• reduce drift of morphologies
• remove alpha to gamma, canny

v1.13.0

#15

• add NCC Template Matching

v1.12.0

#14

• template matching impl (SAD / SSD)
• add benchmarks
• comparing libyuv Rotate mode

v1.11.0

#13

improved performace

• rotate0 / rotate90 / rotate180 / rotate270
• morphology_open / morphology_close / morphology_gradient
• canny canny_dilate canny_morphology_open canny_morphology_close

others

• changed the location of binary and header files to lib/ and include/.
• since there is an overhead when selecting in the Halide function, it was changed to switch in caller.

v1.10.0

#12

• add monophology
• add monophology canny
• fixed problem where the rotate operation was always Rotate90(this fix returned to normal processing speed).
• tune boxblur

v1.9.0

#11

Canny

• sigma is now specified by default
• Canny method have been separated to provide dilate processing(CannyWithDilate).
