A feature of satellite images is the presence of noise, where this noise often requires preprocessing of the images by a denoising method adapted prior to their compression, storage and transmission. In this work to improve the compression scheme, we are interested in image compression by discarding noisy bits from the satellite image and discrete wavelet transform (DWT). This method was tested...

introduction: satellite cells are known as the main regenerative cell type in skeletal muscles. our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. me...

In this paper, we present a method for edge segmentation of satellite images based on 2-D Phase Congruency (PC) model. The proposed approach is composed by two steps: The contextual non linear smoothing algorithm (CNLS) is used to smooth the input images. Then, the 2D stretched Gabor filter (S-G filter) based on proposed angular variation is developed in order to avoid the multiple responses in...
