数据格式不对就没法读取图片信息，可以debug单步看看数据读取到哪一步。
在Python中，我们经常使用Numpy进行矩阵操作，而OpenCV是一个流行的计算机视觉和图像处理库。转换Numpy矩阵到OpenCV图像的过程非常简单，我们可以使用OpenCV中的cv2库的cvtColor函数。
#将Numpy矩阵转换成OpenCV图像
img_cv = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
#显示OpenCV图像
cv2.imshow('image', img_cv)

core: add NEON support for cvFloor in fast_math.hpp #28243
- This PR adds NEON intrinsics-based implementation for the cvFloor function in fast_math.hpp for Windows-ARM64.
- Both float and double overloads now use NEON intrinsics for cvFloor Function.
- calchist and calchist1d function uses cvFloor function for its computations.
- After adding these changes both functions showed improvement in performance.
**Performance Benchmarks:**
