Background Subtraction Through Exhibit Substitution
نویسنده
چکیده
Previous articles have described a process for the elimination of background from fingerprint and other images by subtracting the background. Two options, f iltration and erasure, have been discussed. Channel subtraction, either in RGB (Red, Green, Blue) or HSI (Hue, Saturation, Intensity) mode, can also be effected with variable results. There exists a fourth option: substituting another item of the same type in exact register to obtain a substitute background image for purposes of the subtraction.

متن کاملA Novel Approach to Background Subtraction Using Visual Saliency Map
Generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. Using visual saliency map for modelling gives important information for understanding in many applications. In this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. The proposed technique i...
متن کاملSensory subtraction via cutaneous feedback: a novel technique to improve the transparency of robotic surgery
In this paper we present a novel technique to force feedback in robot-assisted surgery. It consists of substituting haptic force, composed by kinesthetic and cutaneous components, with cutaneous stimuli only. The force generated can be thus thought as a subtraction between the complete haptic interaction, cutaneous and kinesthetic, and the kinesthetic part of it. For this reason, we refer to th...
متن کاملTactile feedback as a sensory subtraction technique in haptics for needle insertion
A sensory substitution technique is presented in which the kinesthetic and tactile feedback are substituted by tactile feedback only provided by two wearable devices able to apply forces to the index finger and thumb holding a handle during a needle insertion task. The force pattern fed back to the user while using the tactile device is similar, in terms of intensity and area of application, to...
