PHI (Protected Health Information) can be present in various data and each format need specific techniques and tools for de-identify it: For Text de-identification is using rule based and NLP (Natural language processing) approaches.
The picture this screenshot is taken from is 1194 pixels wide and 1174 pixels tall. Image sizes on Wikipedia can be determined by doing the following: Go to the image page by clicking on the image thumbnail; Under the image there should be a set of numbers in the form "NNNNxMMMM." This is the size of the image in pixels.
The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image.
For example, a bitmap image may measure 1,000 × 1,000 pixels, a resolution of 1 megapixel. If it is labelled as 250 PPI, that is an instruction to the printer to print it at a size of 4 × 4 inches. Changing the PPI to 100 in an image editing program would tell the printer to print it at a size of 10 × 10 inches.
Pixels per inch (or pixels per centimetre) describes the detail of an image file when the print size is known. For example, a 100×100 pixel image printed in a 2 inch square has a resolution of 50 pixels per inch. Used this way, the measurement is meaningful when printing an image.
Raster graphic image. In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes).
Jimmy Butler #22 of the Miami Heat looks on during the game against the Toronto Raptors on December 1, 2024 at the Scotiabank Arena in Toronto, Ontario, Canada.
In April 2015, Videojet Technologies released their 1650 High Resolution (HR) and 1620 HR Continuous Inkjet (CIJ) printers, said to be capable of printing sub-pixel size characters as small as 0.6 mm in height (equivalent to 1.70079 points). The printers use a 40-micron nozzle that outputs more than 100,000 drops per second of ink. While these ...
