transformation

问题 i want to transform an entire image according to the magnitude of a straight line (y=ax+b) with an angle ( arcTan(a) ) this angle should be applied just to the y axis of all the points. i wanted to use the warpAffine(...) method but what I was able to make work with this method is using points (generally 3) in the image so that warpAffine(...) can figure out the angle for itself and transform that part of the image, and that's not what I need because I want to transform the whole image not

问题 I would like to build a predictive model to predict the following numerical label self.varname_label = ['SUMMED_ALLCAUSE_NUM_POST2YR', 'SUMMED_DXTARGET_NUM_POST2YR', 'SUMMED_ALLCAUSE_COST_POST2YR', 'SUMMED_DXTARGET_COST_POST2YR'] . These refers to 1) the number of healthcare visits post index, 2) the number of healthcare visits for a specific medical condition post index, 3) the cost of healthcare visits post index, and 4) the cost of healthcare visits for a specific medical condition post

问题 I would like to transform the SOAP response body to JSON using WSO2 ESB 4.0.3. I found info on how to configure the ESB for JSON but then what? To put it differently; I would like to have/create a transform mediator that transforms incoming SOAP/XML response into JSON (and actually it woudl be good to have a JSON2XML transform mediator too). Should I develop is as a Groovy script mediator or Java class mediator? The best would be to have it pre-packaged with the ESB as it says it supports

问题 Essentially I a SSIS pkg with an Execute SQL statement that dynamically writes a REPLACE function based on some table values. (ie REPLACE(REPLACE(Col1," * ","",),"@@@","") ExecuteSQL result is put to variable @Cleanse In my Derived Column conversion Im trying to call @User::Cleanse as an expression in to replace the Value of the Col1 from the DataFlow. The result appears to be pulling the result of @Cleanse and using it as a string value rather than applying it as the REPLACE function. When

问题 I'm quite new to the XSLT world and need assistance with the following: A program takes the following string: cn = 'James Bond' and (sn='Bon*' or givenName='Jam*') and generates the following XML which is my input XML that I need to process using a stylesheet. Input XML: <?xml version="1.0" encoding="UTF-8"?> <queryString> <parameters> <parameter id = "1"> <name>cn</name> <value>James Bond</value> <comparativeOperator>=</comparativeOperator> <parens> <leftParen>((</leftParen> <rightParen>)<

问题 I am not sure it's even possible but here it goes. From this XML: <?xml version="1.0" encoding="UTF-8"?> <AttributesCollection> <Attributes> <AttributeName>AAA</AttributeName> <AttributeValue>Value1</AttributeValue> </Attributes> <Attributes> <AttributeName>BBB</AttributeName> <AttributeValue>Value2</AttributeValue> </Attributes> </AttributesCollection> I am looking to convert it to the following using XSL transformation: <Attributes> <AAA>Value1</AAA> <BBB>Value2</BBB> </Attributes> I can

问题 In my app I have 3d transformations by means android.graphics.Camera . It seemed to work fine until I tried Nexus. I installed the app on Nexus 7 (4.2.1) and Galaxy Nexus (4.1.2), both of them don't perform Camera transformation at all. I have two different views with Camera and both show standart animation and doesn't apply Camera transformations. Who can explain such a behaviour? UPD: camera code transformation.clear(); transformation.setTransformationType(Transformation.TYPE_MATRIX);

问题 I have a code that manipulates and renders a QImage onto a QWidget . Manipulation includes typical homogeneous transformations as well as clipping, applying a color-transfer function, etc. Now I have to deform the image onto a four-vertices polygon (a quad), not necessarily a rectangle. To be clear, I'm not talking about clipping the image, but deforming it. I know how to do it using OpenGL (a textured quad), but I wonder if it is possible to do it without switching to OpenGL. Does Qt have

问题 Intro. Previously, I've asked a question on converting rgb triple to quaternion. After that question I've managed to get unit quaternions, but I am in doubt of their internal structure. There was no easy way to operate them, and to separate luma and chroma , since that were quaternions of unit length. According to my feeling about it, luminance should be encoded in the either real part, or a whole magnitude; And color " chroma " information should be encoded in the imaginary part. Today I've

问题 Hello i have two different xml and i want to merge them copying one node from target xml, based on matching source and target xml node value first xml like this: <PRODUCTS> <PRODUCT> <NAME>PRODUCT 1</NAME> <MAINCATID>38</MAINCATID> <SUBCATID>39</SUBCATID> </PRODUCT> </PRODUCTS> Second XML is like this <CATEGORIES> <MAINCATEGORY> <MAINCATID>38</MAINCATID> <MAINCATNAME>CATEGORY 1</MAINCATNAME> </MAINCATEGORY> <MAINCATEGORY> <MAINCATID>37</MAINCATID> <MAINCATNAME>CATEGORY 2</MAINCATNAME> <
