第六章测试1. Image segmentation is the technology and process of dividing an image into several specific regions with unique properties and proposing objects of interest. In the following statement about image segmentation algorithm, the error is （ ）.
A:Region growth method is to complete the segmentation by calculating the mean vector of the offset. B:Watershed algorithm, MeanShift segmentation, region growth and Ostu threshold segmentation can complete image segmentation. C:Watershed algorithm is often used to segment the objects connected in the image. D:Otsu threshold segmentation, also known as the maximum between-class difference method, realizes the automatic selection of global threshold T by counting the histogram characteristics of the entire image
答案:A
2. Camera calibration is a key step when using machine vision to measure objects. Its calibration accuracy will directly affect the measurement accuracy. Among them, camera calibration generally involves the mutual conversion of object point coordinates in several coordinate systems. So, what coordinate systems do you mean by "several coordinate systems" here? （ ）
A:Image coordinate system B:Image plane coordinate system C:Camera coordinate system D:World coordinate system 3. Commonly used digital image filtering methods:（ ）.
A:bilateral filtering B:median filter C:mean filtering D:Gaussian filter 4. Application areas of digital image processing include:（ ）
A:Industrial inspection B:Biomedical Science C:Scenario simulation D:remote sensing 5.
