Глобализация рынка, стремление многих стран к интеграции, формирование транснациональных корпораций и другие политико-экономические факторы потребовали переосмысления роли стандартизации в мире. Одними из основных трудноразрешимых задач, с которыми приходится сталкиваться международной торговой системе, является разнородность методов и способов оценки соответствия, бытующих в разных странах и применяемых в различных условиях. Мировое сообщество ответило усилением роли международных стандартов, принятых на основе консенсуса. Представители развитых стран стараются занять активные позиции в комитетах Международной организации по стандартизации (ИСО), лоббируя интересы «своих» производителей. Одно из следствий отмеченной тенденции-резкий рост числа международных стандартов и сокращение сроков их разработки.

Hozirgi vaqtda turli xil tasvirga olish qurilmalaridan olingan raqamli tasvirlar soni keskin oshib bormoqda. Ayrim hollarda ushbu tasvirlar tasvirga olish, qayta ishlash, siqish, saqlash, uzatish va ko’paytirish jarayonida turli shovqinlardan ta’sirlanib, sifatsiz holatga kelishi mumkin. Shovqin tasvirdagi ma’lumotlarning sifatini buzadigan tasodifiy o’zgarishlarni ifodalaydi va tasvirdan muhim ma’lumotlarni olishga to’sqinlik qiladi. Bu o’z navbatida, tasvirda uchraydigan asosiy shovqin turlarini o’rganish tasvirlash sohasida dolzarb ekanligini ko’rsatadi. Mazkur tadqiqot ishi Gauss, tuz va qalampir, uniform, Puasson, spekl, rayleigh va risian kabi shovqin turlarini o’rganishga bag’ishlangan.
Axborotni qabul qilish va uzatishda tasvirlarning ahamiyati, ayniqsa tibbiyot va qishloq xo’jaligi kabi sohalarda tengsizdir.
