Instancemärkiytyminen

Instancemärkiytyminen, also known as instance grounding or object grounding, is a process in artificial intelligence and computer vision that involves associating natural language descriptions with specific regions or instances within an image or video. It is a crucial step towards enabling machines to understand and interact with the visual world in a more nuanced way. The goal is to pinpoint the exact pixels or bounding boxes that correspond to objects or concepts mentioned in text.

This task typically requires a model to process both visual input and textual input simultaneously. For example, given an image and the sentence "the red ball is on the table," instancemärkiytyminen would aim to identify and highlight the pixels that constitute the red ball. This differs from image captioning, which generates a general description of the entire image, or visual question answering, which answers a question about an image.

Instancemärkiytyminen has applications in various fields. In robotics, it can help robots identify and manipulate specific objects based on verbal commands. In image retrieval systems, it allows for more precise searching using descriptive queries. It also plays a role in human-computer interaction, enabling more intuitive ways to interact with visual data. Research in this area often involves developing sophisticated neural network architectures that can effectively fuse information from different modalities.
