Disadvantages Of Digital Image Processing

1263 Words6 Pages

Digital image processing is a sub part or field of digital signal processing which uses computer algorithms for processing various digital images. By allowing a large range of algorithms to be applied to input data, digital image processing has many advantages over analog image processing. Moreover digital image processing can also deal with problems related to noise and signal distortions at the time of processing. As the images can be defined in more than two dimensions so digital image processing may also be modeled as a multidimensional system.
History of digital image processing dates back to 1960s. At that time digital image processing or say digital picture processing techniques were developed at various research facilities such as Jet Propulsion Laboratory, University of Maryland, Bell Laboratory, Massachusetts institute of Technology and many more. In that era major applications for which digital image processing was used were satellite imagery, videophone, recognition of voice and characters, medical images, conversion of wire-photo standards, image enhancements and many more. The computing equipments at that time were …show more content…

In this era digital image processing grew as now cheaper computers and dedicated hardware was now available which helped in processing images at real time, but that too for some typical problems like television standard conversion. Gradually as the general purpose computers became faster, they were used in the place of dedicated hardware except for few specialized and computer-intensive operations.
In 1994 Space Foundation Space Technology Hall of Fame introduced digital image processing technology for medical applications into their curriculum. Slowly and steadily in 2000s with the availability of fast computers and signal processors, DIP became the most preferred form for processing images. Now it is not only the cheapest way of processing images but also the most versatile

    After, the color space transformation we are going to extracts the texture vector from that image using sparse texture model. The texture vectors are represented as a set of distributions which is used to cluster the texture data using K-means clustering algorithm. Finding the number of clusters which consists set of texture distributions used to calculate TD metric. After, calculating the TD metric, the image is over segmented using SRM algorithm, which results the image being divided into large number of regions. Next, each region is independently classified as representing normal skin or lesion based on the textural contents of that region.

    Soon after during the early 1930’s, the Technicolor Motion Picture Corporation released the first three-color Technicolor technology. This color process needed a unique type of camera that was able to split the image into three different sections of the film. Filters that were red, blue, and green were used to position the light to the matching filter, once the recording was done the different strips were then combined and developed into a solo color strip that was played through a projector. This latest invention of color introduced a whole new aspect in the world of filmmaking. The filmmaker/filmmakers could than provide more information to the audience about the whereabouts and the setting of a scene with the use of color.
