Image Quality Factors (Key Performance Indicators) Imatest

WebMost high-quality cameras provide an infrared (IR) cut-off filter for imaging specifically in the visible spectrum. These filters are sometimes removable for near-IR imaging. Figure 8: Normalized Spectral Response of a Typical Monochrome CCD. CMOS sensors are, in general, more sensitive to IR wavelengths than CCD sensors. Image quality can be assessed using objective or subjective methods. In the objective method, image quality assessments are performed by different algorithms that analyze the distortions and degradations introduced in an image. Subjective image quality assessments are a method based on the way … Meer weergeven Image quality can refer to the level of accuracy with which different imaging systems capture, process, store, compress, transmit and display the signals that form an image.
