卫星图像的同步图像变换问题

Question

我想将单应性应用于卫星图像。我发现这个post非常有帮助。所以我决定使用相同的Matlab代码。

<?php

namespace app\models;

class UserRecord extends \yii\db\ActiveRecord implements \yii\web\IdentityInterface
{
    public $id;
    public $steamid;
    public $username;
    public $profileurl;
    public $avatar;
    public $avatarmedium;
    public $avatarfull;

    public $verified;
    public $banned;
    public $rank;
    public $authKey;

//    public $password;
//    public $accessToken;

    public static function tableName()
    {
        return 'users';
    }

    public function getAuthKey() 
    {
        return $this->authKey;
    }

    public function getId()
    {
        return $this->id;
    }

    public function validateAuthKey($authKey)
    {
        return $this->authKey === $authKey;
    }

    public static function findIdentity($id)
    {
        return self::findOne($id);
    }

    public function validateSteamID($steamid)
    {
        return $this->steamid === $steamid;
    }

    public static function findIdentityByAccessToken($token, $type = null)
    {
        throw new \yii\base\NotSupportedException;
    }

    public static function findBySteamId($steamid)
    {
        return self::findOne(['steamid' => $steamid]);
    }

}

但输出只是小盒子。 我正在使用MATLAB 2015b

修改 使用 im = imread('cameraman.tif'); n = [0;0;-1]; d = Inf theta = 60*pi/180; R = [ 1 0 0 ; 0 cos(theta) -sin(theta); 0 sin(theta) cos(theta)]; t = [0;0;0]; K=[300 0 0; 0 300 0; 0 0 1]; H=K*R/K-1/d*K*t*n'*K; img=imagehomog(im,H','c'); figure;imshow(img) 和imtransform

进行同形

maketform

输出

我怎样才能从中心去做。像这样的东西
