Looming Looming Looming is a term found in the study of perception, as it relates directly to psychology. Looming refers to the rapid expansion in the size of any given image. As the image becomes increasingly large on the perceiver's retina, i.e., when an object "looms", there is an automatic physiological response to perceive the object as an approaching object or surface, instead of one that is stationary or receding. Evidence indicates that looming perception is not limited to the visual modality, but can occur due to auditory or even tactile stimuli. There is a different type of mirage that is
Object categorization from image search the visual words are absolute, changing the size of the object in the image or moving it would have a significant impact on the spatial distribution of the visual words into different bins. Translation and scale invariant pLSA (TSI-pLSA). This model extends pLSA by adding another latent variable, which describes the spatial location of the target object in an image. Now, the position formula_11 of a visual word is given relative to this object location, rather than as an absolute position in the image. The new equation is: formula_16 Again, the parameters formula_17 and formula_14 can be solved using the
