I was wondering if the community would be interested in a modified version of threshold_otsu to incorporate a mask.
I have already implemented this function with an extra keyword which was the mask…

Currently, there is no built-in support in Python's image processing libraries, such as OpenCV or scikit-image, to directly apply Otsu's thresholding algorithm.
I would like to request the addition …

In many (possibly most) of our test cases, we consider an image generated with np.asarray([...]) to be our representation of an image. However, this generates numpy arrays of 64-bit precision.
As I…

cv2.threshold 有點像是np.where
```py
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) # 先將圖片轉為灰階
# 將小於閾值的灰度值設為0,其他值設為最大灰度值。>127 =255, 127 =0, 127 =127
ret,thresh3 = cv2.threshold(img,127,255,cv2.THRESH…

The following code comput…
