Abstract SAI (Soft-decision Adaptive Interpolation)

technique is mainly intended for maintaining theimage clarity even after the image isinterpolated.

Introduction

Abhinav-hitech college of engineering

Our project presents a new image interpolation technique

for enhancement of spatial resolution of images.

The project uses the switching of existing Soft-decision

Adaptive Interpolation (SAI) algorithm and Single Pass

Interpolation Algorithm (SPIA) methods.

Goals

This project will help effectively to interpolate aimage into higher resolutions.

The edges can be shown very effectively and the

blurs can reduced to the maximum extent.

Features Of Our Project

Considering four pixels at a time rather thanconsidering 16 pixels at a time.

Reducing the blurs in the image after resolution.

Edges will be shown very effectively.

Time is reduced.

Existing System

In the Existing System, two basic techniques areused:

Bilinear and Bicubic.

In bilinear, the pixels are placed linearly in thedestination without any manipulations in theimage.

In bicubic, we consider 16 pixels for calculatingthe destination pixel value. This increases thecomplexity in calculating the destination image.

Proposed System

To overcome the drawback of the existingsystem, SAI technique is proposed where 4 pixels

are considered in calculating the destination pixelvalue. This reduces the time complexity ingenerating the interpolated image.

SCOPE OF THE PROJECT

This new image interpolation techniqueoutperforms the existing methods in both bilinearand bicubic techniques, by preserving the edges

while reconstructing the HR image.

The complexity is less compared to the existingsystem. The blurs in the image will be reduced.

The final image will be very effective. Not onlythese the user can also save the image and hasthe option to print the image.

FUTURE ENHANCEMENT

This project gives the interpolated image withoutblurs in it. We can extend this project by giving

different features like editing, cropping, etc.,
