For example, participants in boundary extension experiments often tend to say that the boundary-extended test photos came from the study pictures rather than recognizing that they altered the photos in their minds to cause boundary extension, and these new photos that they are trying to remember were self-generated.

Boundary tracing, also known as contour tracing, of a binary digital region can be thought of as a segmentation technique that identifies the boundary pixels of the digital region. Boundary tracing is an important first step in the analysis of that region. Boundary is a topological notion. However, a digital image is no topological space.
The Markov boundary always exists. Under some mild conditions, the Markov boundary is unique. However, for most practical and theoretical scenarios multiple Markov boundaries may provide alternative solutions. [2] When there are multiple Markov boundaries, quantities measuring causal effect could fail. [3]
A chain code is a lossless compression based image segmentation method for binary images based upon tracing image contours. The basic principle of chain coding, like other contour codings, is to separately encode each connected component, or "blob", in the image.
In computer vision, contour models describe the boundaries of shapes in an image. Snakes in particular are designed to solve problems where the approximate shape of the boundary is known. By being a deformable model, snakes can adapt to differences and noise in stereo matching and motion tracking.
Boundary-value analysis is a software testing technique in which tests are designed to include representatives of boundary values in a range. The idea comes from the boundary . [ 1 ] Given that there is a set of test vectors to test the system, a topology can be defined on that set.
PsychoPy is an open source software package written in the Python programming language primarily for use in neuroscience and experimental psychology research. [2] [3] Developed initially as a Python library and then as an application with a graphical interface, it now also supports JavaScript outputs to run studies online and on mobile devices ...
Floor effects are occasionally encountered in psychological testing, when a test designed to estimate some psychological trait has a minimum standard score that may not distinguish some test-takers who differ in their responses on the test item content. [4]
