From general observations in related areas of biomedical image analysis, it would seem that improved methods for neuron tracing are possible by bridging the dichotomy of global processing versus local exploration algorithms, exploiting the best of both worlds in a multiscale framework, and moving towards probabilistic rather than deterministic image segmentation approaches.

Semantic segmentation focuses on classifying each pixel in an image into a specific category. It assigns a unique class label to each pixel in an image and divides it into one of the predefined set of semantic categories, such as person, car, or tree. However, this segmentation technique does not differentiate between instances of the same class and treats them as a single entity. Imagine coloring a scene where all cars are blue, all people are red, and everything else is green – that's semantic segmentation in action.

Semantic segmentation is a type of image segmentation.

La segmentation sémantique est l'assignation d'une classe à chaque pixel d'une image afin de cerner précisément les éléments qui la composent. Ce procédé diffère de la détection d'objets qui se limite à identifier la position approximative des éléments dans l'image. Bien que plus difficile, ce niveau de précision a ses avantages. Par exemple, lors de l'application sélective d'herbicide, la proximité des plantes est un enjeu important. Le simple rectangle autour d'une cible probable n'est plus suffisant, car il peut mener à une application sur les mauvaises espèces.

La segmentation sémantique est un type de segmentation d'images.

In the context of computer vision, panoptic segmentation aspires to capture "everything visible" in an image. It achieves this by combining the capabilities of semantic segmentation, which assigns a class label to each pixel(e. g., car, person, tree), and instance segmentation, which identifies and separates individual object instances within a class(e. g., distinguishing between multiple cars in an image).

Le concept de segmentation panoptique a été introduit en 2019 afin d'unifier les concepts de segmentation sémantique et d'instances. C'est un concept récent, et pour l'instant il existe relativement peu de réseaux qui permettent de réaliser une telle segmentation. D'une manière générale, ces réseaux réalisent une segmentation sémantique et une segmentation d'instances sur une même image d’entrée, puis fusionnent les sorties des deux segmentations.

Another important subject within computer vision is image segmentation. It is the process of dividing an image into different regions based on the characteristics of pixels to identify objects or boundaries to simplify an image and more efficiently analyze it. Segmentation impacts a number of domains, from the filmmaking industry to the field of medicine. For instance, the software behind green screens implements image segmentation to crop out the foreground and place it on a background for scenes that cannot be shot or would be dangerous to shoot in real life

La segmentation d'images constitue la base de nombreuses tâches de vision par ordinateur[,] comme la détection d'objets et la classification d'images. C'est une méthode qui consiste à diviser une image en sous-groupes. Cette division s'effectue habituellement en fonction du contour ou des limites visibles des objets dans une image afin d'en réduire la complexité. [...] La segmentation d'images a plusieurs utilités dans les domaines des véhicules autonomes, de l'analyse d'images médicales et d'images satellites, de la vidéosurveillance et d'autres tâches de reconnaissance et de détection.

Instance segmentation goes a step further [than semantic segmentation] by not only identifying the category of an object but also delineating its individual boundaries. This allows us to distinguish between multiple instances of the same class. For example, if an image contains multiple cars, instance segmentation would assign a unique label to each car, distinguishing them from one another.

[...] il est pertinent de décrire la différence entre la segmentation sémantique et la segmentation d'instance. La segmentation sémantique cherche à décrire de quelle classe sont les pixels d'une image, sans être capable toutefois de faire la différence entre plusieurs éléments d'une même classe dans une image. La segmentation par instance ajoute cette couche d'information supplémentaire aux prédictions, c’est-à-dire pouvoir déterminer les frontières entre plusieurs éléments de la même classe.

Object-Based Image Analysis(OBIA) employs two main processes, segmentation and classification. Traditional image segmentation is on a per-pixel basis. However, OBIA groups pixels into homogeneous objects. These objects can have different shapes and scale. Objects also have statistics associated with them which can be used to classify objects.
