In Machine Learning and Computer Vision, M-Theory is a learning framework inspired by feed-forward processing in the ventral stream of visual cortex and originally developed for recognition and classification of objects in visual scenes. Ultimately, practical object recognition systems will have to be trained on natural images. The value of the present approach is to allow systematic objective compar-isons shape classiﬁcation methods, as well as a way of assessing their invariant properties, and the number of ex-amples required to train them.

Fast visual recognition in the mammalian cortex seems to be a hierarchical process by which the representation of the visual world is transformed in multiple stages from low-level retinotopic features to high-level, global and invariant features, and to object categories.
Every single step in this hierarchy seems to be subject to by: learning the parameters of the scale-invariant object model are estimated. This is done using expectation-maximization in a maximum-likelihood setting.
In recognition, this model is used in a Bayesian manner to classify images. The ﬂex-ible nature of the model is demonstrated by excellent re-sults over a range of datasets including geometrically con. Learning Location Invariance for Object Recognition and Localization.
A visual system not only needs to recognize a stimulus, it also needs to find the location of the stimulus.

Invariant object recognition refers to recognizing an object regardless of irrelevant image variations, such as variations in viewpoint, lighting, retinal size, background, etc. The perceptual result of invariance, where the perception of a given object property is unaffected by irrelevant image variations, is often referred to as perceptual constancy (Kofka, ; Walsh and Cited by: 5.

Objects are modeled as flexible constellations of parts. A probabilistic representation is used for all aspects of the object: shape, appearance, occlusion. Topics will include part-based models for recognition, invariant local features, bags of features, local spatial constraints, shape descriptors and matching, learning similarity measures, fast indexing methods, recognition with text and images, the role of context in recognition, and unsupervised category discovery.
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
The following outline is provided as an overview of and topical guide to object recognition. Object recognition – technology in the field of computer vision for finding and identifying objects in an image or video sequence.
Humans recognize a multitude of objects in images with little effort, despite the fact that the image of the objects may vary somewhat in different view. Invariant visual object recognition is the ability to recognize visual objects despite the vastly different images that each object can project onto the retina during natural vision, depending on its position and size within the visual field, its orientation relative to the viewer, etc.
Achieving invariant recognition represents such a formidable computational Cited by: These results provide previously unknown latencies for key stages of human-invariant object recognition, as well as new and compelling evidence for a feed-forward hierarchical model of invariant object recognition where invariance increases at each successive visual area along the ventral stream.
