In image thresholding, what is the purpose of the "THRESH_BINARY" technique?

• It converts an image to grayscale.
• It converts an image to binary format
• It applies a color map to an image
• It increases the image resolution

Which library in Python is commonly used for image processing and thresholding techniques?

• NumPy
• Matplotlib
• OpenCV
• Pandas

Which argument is used to specify the source image when applying the "THRESH_BINARY" technique in OpenCV?

• src_img
• src_image
• src
• source

In OpenCV, what is the typical range of pixel values for binary images created using "THRESH_BINARY"?

• 0 to 1
• 0 to 255
• -1 to 1
• 0 to 100

What happens to pixel values in the "THRESH_BINARY" technique if they are greater than the specified threshold value?

• They become 0.
• They become 255.
• They become negative.
• They remain unchanged.

Which thresholding technique in OpenCV can be used to create a binary image where pixels below the threshold are set to 255 and pixels above the threshold are set to 0?

• THRESH_BINARY
• THRESH_TRUNC
• THRESH_TOZERO
• THRESH_BINARY_INV
