Abstract:	This article presents an interactive color object extraction scheme based on pixels extracting where users outline the desired objects on the input original RGB color image as the original seeds. The proposed algorithm analyzes the distribution of seeds in the neighboring region of a seed to automatically generate an adaptive forecasting filter and the corresponding threshold vector. The filter utilizes its corresponding threshold vector to identify the pixels which resemble the desired object. These identified pixels are added to seeds set and can then be used as seeds to extract other pixels. The extrac tion steps are repeated according to the modified significance linked connected component analysis (SLCCA) scheme until all the seeds in the set are used. Finally, the coordinates of seeds of the final seeds set are transformed to the original input RGB color image to extract the desired objects. In the experiment, several measures of errors, such as ME, RFAE, EMM, EER, MHD, are conducted to measure the performance of the proposed algorithm. The experimental results show that (a) the proposed algorithm can simultaneously and efficiently extract multiple desired objects from an RGB color image even though the background complexity and the number of seeds is small (one seed only); (b) the proposed algorithm is simpler and saves more time than the MSRM scheme [19] with the same precision; (c) the proposed algorithm is very accurate and efficient compared with the DTS scheme [18]. © ICIC International 2011.
