Photo-text , also written as photo/text , is a hybrid form of artistic expression that combines photography and textual elements to convey a message or create a narrative.
Analogy text-image. Visual words, as used in image retrieval systems, [1] refer to small parts of an image that carry some kind of information related to the features (such as the color, shape, or texture) or changes occurring in the pixels such as the filtering, low-level feature descriptors (SIFT or SURF).
Feature detection includes methods for computing abstractions of image information and making local decisions at every image point whether there is an image feature of a given type at that point or not. The resulting features will be subsets of the image domain, often in the form of isolated points, continuous curves or connected regions.
In analyzing a text that includes an image of the bald eagle, as the main body of the visual text, questions of representation and connotation come into play. Analyzing a text that includes a photo, painting, or even cartoon of the bold eagle along with written words, would bring to mind the conceptions of strength and freedom, rather than the ...
In publishing, a callout or call-out is a short string of text connected by a line, arrow, or similar graphic to a feature of an illustration or technical drawing, and giving information about that feature. The term is also used to describe a short piece of text set in larger type than the rest of the page and intended to attract attention.
In computer vision, the bag-of-words model (BoW model) sometimes called bag-of-visual-words model [1] [2] can be applied to image classification or retrieval, by treating image features as words. In document classification , a bag of words is a sparse vector of occurrence counts of words; that is, a sparse histogram over the vocabulary.
In computer vision, visual descriptors or image descriptors are descriptions of the visual features of the contents in images, videos, or algorithms or applications that produce such descriptions. They describe elementary characteristics such as the shape , the color , the texture or the motion , among others.
The following tables list the features defined in version 1.8.1 of the OpenType specification. The codes in the "type" column are explained after the tables. OpenType features may be applicable only to certain language scripts or specific languages, or in certain writing modes. The features are split into several tables accordingly.
