Background Image Generation Using Boolean Operations
نویسندگان
چکیده
Tracking moving objects from a video sequence requires segmentation of these objects from the background image. However, getting the actual background image automatically without object detection and using only the video is difficult. In this paper, we describe a novel algorithm that generates background from real world images without foreground detection. The algorithm assumes that the background image is shown in the majority of the video. Given this simple assumption, the method described in this paper is able to accurately generate, with high probability, the background image from a video using only a small number of binary operations.

A Method of Solving Pattern or Image Recognition Problems by Learning Boolean Formulas
A method of solving supervised pattern recognition problems based on the model of learning Boolean formulas is suggested. It is proved that this method of learning is of NP-complexity. An eecient learning procedure using some tools of combinatorics and graph theory is proposed. The suggested method diiers from those known in its diminished number of computational operations. The results obtaine...
متن کاملArtificial color image logic
Artificial Color is simply biomimetic spectral sensing and processing to achieve spectral discrimination. Using Artificial Color means to construct image plane filters; we can then perform logic operations on those filters before applying them to scenes. Boolean and fuzzy logic can both be used. We illustrate the concept by the Boolean AND of two such masks applied to a complex scene. 2003 Else...
متن کاملA PRACTICAL APPROACH TO REAL-TIME DYNAMIC BACKGROUND GENERATION BASED ON A TEMPORAL MEDIAN FILTER
In many computer vision applications, segmenting and extraction of moving objects in video sequences is an essential task. Background subtraction, by which each input image is subtracted from the reference image, has often been used for this purpose. In this paper, we offer a novel background-subtraction technique for real-time dynamic background generation using color images that are taken fro...

متن کاملThreshold visual secret sharing based on Boolean operations
We design a new (k,n)-threshold visual secret sharing scheme on the basis of Boolean operations. We propose two different algorithms to encrypt a secret image into n meaningless shares such that no secret information can be obtained by having any k 1 or fewer shares. However, the secret image can be reconstructed easily by XOR of any k (≤n) or more shares. Both the algorithms have used simple B...
