The Optimal Pixel Adjustment Process is applied after embedding the message. We employed frequency domain to increase the robustness of our steganography method. Integer wavelet transform avoids the floating point precision problems of the wavelet filter. We use Integer Wavelet Transform and Optimal ...
while the other stands along the railing with a glimpse of the neighborhood in the background. In the 400-pixel vertical version, both daughters sit on the steps with the dog next to one of them with both railings visible. In the 200-pixel vertical version, each daughter and the dog hav...
In all scenarios, a steep increase in retrofitting costs is observed at the transition from Pareto point 4 to the CO2-optimal point, suggesting a significant adjustment of the retrofitting strategy at that point. In comparison to the other two scenarios, the increase in the Decentralized scenario...
the J equation discussed above) to adjust luminance values. In some implementations, the following luminance mapping algorithm may be used: (1) calculate pixel luminance; (2) transform the luminance values into lightness values using the luminance-to-lightness curve; (3)...
wherein I(x,y) is the image pixel value as a function of the Cartesian coordinates x and y, or is the image intensity map as a function of the coordinates x and y. For the purposes of the present invention, the terms “image intensity map” and “intensity map” refer interchangeably...
All of those pixel assignments must be transmitted via the communications system. Such a transmission requires large amounts of communication time. Further, if movement is depicted in the display, information must be continuously sent over the communications system to refresh the image or, in the ...

While the nodes in the map space remain fixed, the learning process entails adjusting the weight vectors towards the input data, typically by reducing a distance metric like Euclidean distance. Importantly, this adjustment must not disrupt the topology established by the map space. Following the ...
The optimization process is called bundle adjustment and is the step at which GCPs are incorporated. The objectives of incorporating GCPs are twofold. First, it can help constrain the non-linear cost function and refine the camera parameters and keypoint positions. Second, it helps georeference ...
