A Study of Openings and Closings with Reconstruction Criteria
نویسندگان
چکیده
In this paper, a class of extended lower and upper levelings is investigated. Here, some conditions are imposed to the criteria for building extended lower and upper levelings in order to generate openings and closings with reconstruction criteria. The idea of building these new openings and closings comes from the notions of morphological filters by reconstruction and levelings. The main goal in studying these transformations consists in eliminating some inconveniences of the morphological opening (closing) and the opening (closing) by reconstruction, and to show the interest in image segmentation. In fact, while the morphological opening (closing) modifies the remaining structures, the opening (closing) by reconstruction sometimes reconstructs undesirable regions.

متن کاملImage segmentation and filtering based on transformations with reconstruction criteria
In this paper, a class of transformations with reconstruction criteria, derived from the reconstruction transformations, is investigated. The idea to build these transformations consists in stopping the reconstruction process according to a size criterion. This class of transformations was initially proposed for obtaining intermediate results between the morphological opening and the opening by...

متن کاملGeneralized Hit - Miss Operators with Applications to Document Image Analysis
The morphological operators of a hit-miss transformation, opening, and closing are generalized in a number of ways. The new operators are useful for solving a variety of binary image analysis problems that involve pattern detection and reconstruction. Generalized openings are developed by replacing erosions with hit-miss operators. These new openings are shown to be anti-extensive, idempotent, ...

The food environment is increasingly hypothesized to cause obesity. This study investigates the impacts of access to supermarkets, the primary source of healthy foods, on the bodyweight outcomes of children. The empirical analysis uses a statewide individual-level panel data set covering health screenings of public schoolchildren along with annual georeferenced business lists and utilizes the p...
