2 ANN-Based Scene Classification

The problem of scene classification has been studied for many years. There are many approaches based on neural networks, where an ANN using huge amount of images learned to recognize the type of given scene (for example, a kitchen, a bedroom, etc.). For this case several datasets are available. One example is [11], but it does not specify locations, so this and similar datasets are not usable for our task.

However, our classification problem is different. We want to train an ANN able to recognize a particular location (for example “Springfield-EverGreenTerrace-742- floor2-bathroom”), which can me recorded by camera from many angles (typically, some object can be occluded by other objects from some angles).

One approach using ANN to solve this task is described in [1], there convolutional networks were used. The difference to our approach is on the one hand in the extraction and usage of video images, on the other hand in types of ANN layers.

Another approach is described in [4]. The authors propose a high-level image representation, called Object Bank, where an image is represented as a scale-invariant response map of a large number of pre-trained generic object detectors. Leveraging on the Object Bank representation, good performances on high level visual recognition tasks can be achieved with simple off-the-shelf classifiers such as logistic regression and linear SVM.
