Case-based reasoning (CBR) is appropriate for medical applications beacause 1) medicine uses a combination of qualitative and quantitative data, 2) CBR is not as prone to errors with exceptions or errors over-generalization, 3) it easily accomodates changes in the subject area, and 4) all CBR decision steps are understandable to a human decision-maker.

hypothesis: one has to deploy image-based knowledge discovery in order to identify many possible features that describe the quality of oocytes and embryos.[53]

In this work they create visual descriptions from images. In this way it's changing from one visual representation to another.

morphometry: techniques for the measurement of the size and shape of biological structures.

Visual aspects of eggs (oocytes) and embryos can help with the in-vitro fertilization (IVF) process. This work automates morphometry to identify features like cytoplasmic inclusions and granularity, size of the perivitelline space, cell number, cell membrane regularity, fragmentation, compaction, zona pellucide thickness. This extracted information is linked to more traditional symbolic information to better predict pregnancy outcome.

Two main ways to do segmentation (telling what objects are in an image) are region-oriented (clustering areas of same-color) and edge-oriented (looking for abrupt changes in color to demarcate object boundaries). In this work, the KB is used to know which kinds of objects might have fuzzy boundaries.[55]

The limitations of computational vision techniques means that retrieval is either based on expert annotation or simple image characteristics like color, shape, and shade. This work uses deformable models.

deformable models: Available models are recognized and the task is to align and deform the new model to fit it. Somehow, deformable models can also be used or feature extraction. 11 features are found for the eggs and 4 for the embryos in this work. It uses "snakes." TA3 is used for retrieval.[56]
