Using fuzzy techniques for intensity transformation and spatial filtering 第3章 第*页 3.3 Histogram processing Motivation Intensity transform can enhance image because it properly changes the image histogram. So w

A novel dual cloud server privacy-preserving scheme in spatial crowdsourcing 2024, Computers and Security Citation Excerpt : Sadly, these fake locations sometimes lead to filtering failures, thus limiting further improvements in efficiency. Zhou et al. (2023) proposed a flexible privacy-preserving frame...
The collapse of a laser beam propagating inside a hollow-core fiber is investigated by numerically solving different nonlinear propagation models. We have identified that the fiber confinement favors the spatial collapse, especially in case of pulses wit

However, CNNs are successfully used as 1D CNN in signal processing such as speech recognition and noise filtering. In these cases, the input of 1D CNN is illustrated as a vector (or n × 1 array). Thus, the dimensionality of this spectral signature of HSI data is applied to CNN ...
In addition to sparse data compaction, we also describe several schemes for encoding the spatial positions of these sparse samples. Specifically, we introduce domain bits, position tags, and parameterized position hashes. Filtering and blocking. For applications that require continuous local interpolation...
