Using isophotes and shadows to interactively model normal and height fields
We introduce an interactive modeling tool for designing (a) a smooth 3D normal field from the isophotes of a discretely shaded 2D image and (b) lifting the normal field into a smooth height field given a cast shadow. Block or cartoon shading is a visual style in which artists depict a smoothly shaded 3D object using a small number of discrete brightness values, manifested as regions or bands of...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولHeight Determination of Extended Objects Using Shadows in SPOT Images
Building heights were estimated with relatively high accuracy using shadows in a set of single-look SPOT panchromatic and multispectral images taken from the same satellite simultaneously. Shadows cast b y rows of trees in SPOT images were first used to estimate mean heights of trees. Calibration lines were then constructed to relate the actual mean heights of rows of trees to the estimated hei...

15 صفحه اولAutomated Hedcut Illustration Using Isophotes
In this work, we present an automated system for creating hedcut illustrations, portraits rendered using small image feature aligned dots (stipples). We utilize edge detection and shading cues from the input photograph to direct stipple placement within the image. Both image edges and isophotes are extracted as a means of describing the image feature and shading information. Edge features and i...
