Fast Filtering Problems in Computer Vision Computer Vision in One Slide 1 Extract some features from some images 2 Use these to formulate some hopefully linear constraints 3 Solve a system of . Photography Requirements. Explain how the following elements and terms affect the quality of a picture: . Light -- natural light/ambient, flash . Exposure -- aperture (f-stops), shutter speed, depth of field . Sharpening. Sharpening. Boost detail in an image without introducing noise or artifacts. Undo blur. due to lens aberrations. slight misfocus. Recall Denoising. Input. =. Signal. +. Noise. Photography creates perceptions. It stands for a message that is vital an important. Photography creates lasting memories, it captures moments that are valid and important. Photography is a balance of technique, science and art. And it is access to people and their emotions. Photography is a powerful tool that gives you opportunities to communicate in a highly emotional way. http://www.santomarco.com/. http://michaelleadbetter.com.au/portfolio-Landscape-Photography-Brisbane.html.

What is Photography?. the art, science, and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.. 1. Image. Rich info. from visual data. Examples of images around us. natural photographic images; . . artistic and engineering drawings. scientific images (satellite, medical, etc.). “Motion pictures” => video. Jessica Seth. Pinhole Camera. A pinhole camera is a camera without a lens. It is made out of a light-proof box, usually black with one small hole on one side of the box. On the opposite side of the hole, you place photograph paper where an image can be projected on. Light passes through the hole and enters the box and projects an image of the scene on the photograph paper on the opposite side on of the box. . Fast Filtering Continued. Filtering by . Resampling. This looks like we just zoomed a small image. Can we filter by . downsampling. then . upsampling. ?. Filtering by Resampling. Filtering by Resampling. Divya Spandana . Marneni. Agenda.
