Esempi di utilizzo di DOWNSAMPLING in una frase

• Pearlman in 1996, the non- or undecimated wavelet transform (where downsampling is omitted), and the Newland transform (where an orthonormal basis of wavelets is formed from appropriately constructed top-hat filters in frequency space).
• In digital signal processing, downsampling, compression, and decimation are terms associated with the process of resampling in a multi-rate digital signal processing system.
• Upsampling requires a lowpass filter after increasing the data rate, and downsampling requires a lowpass filter before decimation.
• Adam7 is a multiscale model of the data, similar to a discrete wavelet transform with Haar wavelets, though it starts from an 8×8 block, and downsamples the image, rather than decimating (low-pass filtering, then downsampling).
• After that is the implementation of SWT, its purpose is to mitigate the information loss produced by the downsampling in each DWT subband.
• According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.
• More specific types of resampling include: upsampling or upscaling; downsampling, downscaling, or decimation; and interpolation.
• Horizontal downsampling is used in preference to vertical downsampling because vertical downsampling would break any interlacing, and also because cathode-ray tube (CRT) displays (which were still common when the HD formats were standardised) scan horizontal rows continuously, but vertical lines discretely, making changes to vertical resolution more visible on such displays.
• Initial implementations of full-scene anti-aliasing (FSAA) worked conceptually by simply rendering a scene at a higher resolution, and then downsampling to a lower-resolution output.
• Deep learning architectures for convolutional neural networks (CNNs) with convolutional layers and downsampling layers began with the Neocognitron introduced by Kunihiko Fukushima in 1979, though not trained by backpropagation.
• This feature aims at increasing the quality of displayed picture, by rendering the scenery at a higher and more detailed resolution (upscaling), and scaling it down to match the monitor's native resolution (downsampling).
• Multidimensional Filtering, downsampling, and upsampling are the main parts of multidimensional multirate systems and filter banks.
• However, the camera uses pixel skipping (which is necessary since ProRes RAW directly stores non-debayered sensor data) resulting in a somewhat softer image with more noise and more frequent appearance of moiré patterns compared to the full-width downsampling 8- and 10-bit modes.
