In the modified local-thresholding rule, a pixel is set to 1 if

If the gradient angle at a point is

Two images A and B are combined to form a new image C=0.25A+0.75B. Which statement is most accurate?

A lab must choose between two model families for a project. The data are limited, but the task demands realistic synthetic image generation for augmentation. Labeled data are scarce, and the team is also concerned about training instability and the need for explicit control over outputs. Which conclusion is most appropriate?

Let the

The boundary of a binary set A is defined by

What is the smoothed color vector at the center if a 3-pixel neighborhood contains the RGB vectors (0.2,0.5,0.8), (0.4,0.1,0.2), and (0.3,0.7,0.4)?

In moving average thresholding,

Suppose the Laplacian mask being used has a negative center coefficient, and at one pixel, the original image value is while the computed Laplacian is

Let R denote the full image region, partitioned into subregions . According to the definition of segmentation, which statement must be true for a valid segmentation?
