AKAZE

[tonbo01]

Hi.
I'm trying to use AKAZE with Delphi, but I haven't been successful so far.
I would appreciate any advice you can provide.
Ultimately, I'd like to achieve the following, but I'm stumbling at the beginning with
akaze = cv2.AKAZE_create().

import numpy as np
import cv2

ref_img = cv2.imread('Lenna.bmp')
float_img = cv2.imread('Lenna45.bmp')

akaze = cv2.AKAZE_create()
float_kp, float_des = akaze.detectAndCompute(float_img, None)
ref_kp, ref_des = akaze.detectAndCompute(ref_img, None)

bf = cv2.BFMatcher()
matches = bf.knnMatch(float_des, ref_des, k=2)

good_matches = []
for m, n in matches:
if m.distance < 0.5 * n.distance:
good_matches.append([m])

matches_img = cv2.drawMatchesKnn(
float_img,
float_kp,
ref_img,
ref_kp,
good_matches,
None,
flags=cv2.DrawMatchesFlags_NOT_DRAW_SINGLE_POINTS)

cv2.imwrite('matches.jpg', matches_img)

ref_matched_kpts = np.float32(
[float_kp[m[0].queryIdx].pt for m in good_matches]).reshape(-1, 1, 2)
sensed_matched_kpts = np.float32(
[ref_kp[m[0].trainIdx].pt for m in good_matches]).reshape(-1, 1, 2)

H, status = cv2.findHomography(
ref_matched_kpts, sensed_matched_kpts, cv.RANSAC, 5.0)

warped_image = cv2.warpPerspective(
float_img, H, (float_img.shape[1], float_img.shape[0]))

cv2.imwrite('warped.jpg', warped_image)
