A Spatial Domain Method in computer science refers to techniques that involve making changes directly to the pixels of an image to embed data, with the aim of creating a stego image that is visually indistinguishable from the original cover image. These methods are primarily focused on hiding inf...

Digital image steganography survey and investigation (goal, assessment, method, development, and dataset) 3.2.1 Spatial Domain The spatial domain is the most widely used in image steganography research. Embedding messages using the spatial domain is relatively simple because it can be done directly by...

In summary, Spoint, Splane, and Scube accomplished three analysis tasks of ST data in turn: cell type deconvolution, spatial domain identification, and 3D architecture construction. We have carefully designed each module of our method in an innovative way to address the potential limitations of cur...
We compared the PP test with the only existing method for subcellular colocalization detection, the Colocalization Quotient used by Bento34, finding the latter to exhibit significantly greater FPR estimated as above (>90% Fig. 2a) and lower reproducibility (<10%, Supplementary Fig. ...
